Description

Internal combustion engine and / or equipment for greenhouse gas emission reduction measures

An internal combustion engine that contributes to the reduction of greenhouse gas emissions, particularly producing carbon C and water H ₂ O, mainly plant, into synthesis gas (H ₂ + CO) in the internal combustion engine, Further, carbon dioxide discharged from the combustion of the synthesis gas is separated as fuel for the internal combustion engine and reformed into synthesis gas H ₂ + CO and hydrogen in the internal combustion engine, and the synthesis gas and hydrogen are used as fuel for the internal combustion engine. To do.

Greenhouse gases are a major cause of global warming, and it is a common recognition in the world to think that “greenhouse gases should be reduced.” However, it is at the stage of “specific numerical targets…” Now, in the era of international price competition, the situation is not progressing because it will incur greenhouse gas reduction costs.
Power sources for automobiles (internal combustion engines) that are subject to greenhouse gas emission reduction measures as of 2014 are electric cars, hybrids with hydrogen, or those using only hydrogen or "bioethanol" as fuel. There is also a technology for reducing greenhouse gas emissions by reforming the fuel of engine system Japanese Patent Laid-Open No. 2008-298030 and “bioethanol” into a fuel containing hydrogen and carbon monoxide and using the reformed gas as a fuel. However, it is recognized that there are still problems that must be solved in order to commercialize the products using the prior art, and that each problem has a part that lacks decisiveness in the course of solving.
Of the technologies mentioned above, in the technology using electricity as the power source, according to the statistics of the Electricity Federation of 2011, about 82% of Japan's total power generation is thermal power generation. since the discharging "CO _2" and using the fossil fuels, including unless realized measures that do not emit "CO _2" from the power plant, a greenhouse global warming electricity as a power source It cannot be said that it is a power source of the internal combustion engine that contributes to the reduction of the effect gas. Moreover, nuclear power generation is a power source that does not emit “CO ₂ ”, which uses electricity as the power source of the above technology to reduce greenhouse gases. However, there is a problem of “Fukushima nuclear power plant”, so it is difficult to establish a new one. And I think that the view that it goes to the direction of decommissioning occupies a lot.

Equipment for reducing the “CO ₂ ” already exists, and the method is a proposal to sequester the discharged carbon dioxide deeply (A) or sequestered (B). The world's largest coal-fired power plant in the United States was completed in 2014, but the treatment of “CO ₂ ” emitted by this power generation is a structure (A) that can be contained in a 1500 m underground layer. However, there is a problem that the construction cost of the plant is twice as high as usual, and there is an additional energy cost for containment in the 1,500m underground layer, which is added to the electricity bill and becomes a consumer burden.

Various technologies have been proposed one after another for the energy conversion of blast furnace gas / converter gas in steel mills to obtain synthesis gas or hydrogen gas by reforming “CO ₂ ”. There are many technologies that have been put to practical use, and the gas emitted in the power generation process of thermal power plants is also used to increase energy efficiency, but most of them are fixed-form features in the large-scale equipment industry. There is no proposal of a feasible technique for reforming “CO ₂ ” discharged from the internal combustion engine in the internal combustion engine that can be mounted on the moving form and using it as a fuel for the internal combustion engine.

And a hydrogen outflow direction setting means for setting the hydrogen injection direction so as to flow out toward the central region of the working chamber in the compression stroke in the high rotation range (for example, Patent Documents) 6). * Since hydrogen gas and carbon monoxide in the synthesis gas of the present application are almost equivalent in terms of energy, that is, the (higher) calorific value is almost the same, the structure of the internal combustion engine uses the synthesis gas of the present application as fuel. Has taken up the prior literature describing the structure using hydrogen as fuel in a rotary engine because it is optimal.

In the combination of the present invention, carbon C of the synthesis gas generating material when the reforming means for reforming carbon dioxide is used may be fossil fuel use (for example, coal etc.), and greenhouse gas reduction and emission It is a reduction measure.

The biggest challenge is the reduction of CO ₂ emissions to cope with global warming. By using mainly plant carbon C as a fuel, one of the challenges for reducing greenhouse gases, which is the subject of this application, is The internal combustion engine of the greenhouse gas reduction measures can be configured, and the CO ₂ generated mainly by the combustion of the carbon C of the plant is also reformed into fuel, and the CO ₂ is also converted into fuel. As a result of the quality improvement, the effect of further reducing greenhouse gas emissions and fuel consumption has been increased (for example, 20Km / L is not increased to 25Km / L, but doubled to 40Km / L or more). This is the biggest effect.

Generating this synthesis gas, and using this generated synthesis gas as a fuel, carrying out this project has a great effect on power supply.

It is discarded in the manufacturing process and becomes the starting material of the reforming path of hydrogen (H ₂ ) and carbon monoxide (CO) extraction path, synthesis gas generation path, reforming path, or syngas reforming path By using any one or more of the materials or the materials that serve as the reforming heat source of the reforming path, a configuration in which the auxiliary fuel use control structure that has been supplied to the internal combustion engine is not required is possible.

The CO ₂ produced by burning the carbon of the plant is also generated in the synthesis gas to further reduce the greenhouse gas CO ₂ from the carbon neutral of the Kyoto Protocol on the use of carbon of the plant. CO ₂ can be reduced, and it produces the maximum effect as a greenhouse gas reduction measure that could not be implemented with the existing technology.

Furthermore, even if the carbon of the internal combustion engine of the present application is used as fossil fuel carbon, it has a great effect of reducing CO ₂ by at least several tens of percent even if it cannot cut 100%.

While the purchase of greenhouse gas CO ₂ allowances is revitalizing, Japan's purchase amount is estimated to be about 1 trillions of billions, but this purchase amount can be reduced by several tens of percent.

The endothermic reaction efficiency can be obtained by operating the engine under the constant endothermic reaction condition by operating the engine under the “constant and fuel-efficient conditions” (different conditions at start-up) that are not related to the engine load fluctuation described in the fifth invention. The improvement of fuel efficiency (Km / L) is achieved by making the fuel efficiency good and the fuel efficiency is good.

By providing a cycle (first invention) for generating carbon dioxide in the exhaust gas into synthesis gas, the “CO ₂ ” discharged from the internal combustion engine of the second invention is reformed into fuel. This is the effect of reducing CO ₂ emissions and improving fuel efficiency. * The above effect could be obtained by providing means for reforming water H ₂ O and CO ₂ into fuel.

A radiator including the engine block cooling water passage and the cooling water piping of the internal combustion engine is not necessary.

Current thermal power and nuclear power plants need to be adjacent to the water source, but the location conditions of the power generation facility of this application do not need to be adjacent to the water source and can be installed as close to the power demand area as possible, so there are very few transmission / reception facilities I was able to do it.

The proportion of the Japanese economy affected by fossil energy price fluctuations (and exchange rate fluctuations) will be reduced.

The internal combustion engine according to any one of the first to third aspects of the present invention is used for automobiles (including two-cycle two-wheeled vehicles and four-cycle two-wheeled vehicles), marine and railway diesel engine vehicles, construction machinery, munitions weapon vehicles, and munitions weapons. It is implemented in the form of being mounted on a transportation device such as a ship, and the form in which the power generator is used as an alternative to the thermal power generation facility, or steam that has finished the role of turning the turbine in the existing thermal power generation facility, is newly input The carbon to be introduced is introduced into the endothermic reaction flow path of the internal combustion engine and used for the fuel shortage, and is combined with the existing thermal power generation facility, or one or more of heat, steam, carbon dioxide, or hydrogen It is one of the embodiments using the above-described reforming technology in the manufacturing industry in which either one is discarded.

Each dimensional relationship in the drawings is enlarged for important portions, exaggerated where details are difficult to understand, and reduced when describing wide portions or portions that are less important in the present invention. Thus, the dimensions between and within the drawings are not proportional, and are not actual or scaled.
If the distance between the lines is narrow, it is likely to become a single line that is black and thick at the scanning stage. Therefore, the distance between the lines is widened or described with a single line.

Furthermore, parts other than the basic (main) mechanism of the present invention are omitted between the drawings.

Hydrogen and carbon monoxide are almost energetically equivalent, that is, the (higher) calorific value is almost the same. Therefore, the detailed description in the specification of the present application refers to a known technique using hydrogen as a fuel. There are many. Furthermore, there are many parts that cite known techniques for the technique of reforming “CO ₂ ” into synthesis gas.
The main structure of this application refers to a variety of known technologies (including some that are patent-registered and alive), but cannot be obtained by individual known technologies alone. As a result of skillfully combining the components in order to obtain the effect in this application, it was possible to obtain a surprising effect in terms of reducing greenhouse gas emissions and improving fuel consumption.

Many reforming techniques using methane in addition to dimethyl ether as a hydrocarbon compound have been disclosed, and the hydrocarbon compound can be changed to methane.

The carbon dioxide absorption means (A) and carbon dioxide separation / extraction means (B) for absorbing carbon dioxide by an absorbent material, which are known in the art, are described in JP-A-2010-526759, Japanese Patent No. 33455782, and Japanese Patent Laid-Open No. 2009-2009. -77457, Japanese Patent Application Laid-Open No. 2001-213545, Japanese Patent Application Laid-Open No. 2007-177684, and the like (B) are disclosed in Japanese Patent Application No. 2001-48591 (Karman vortex), Japanese Patent Application Laid-Open No. 2007-177684, etc. The prior art of the method for producing hydrogen and carbon monoxide by carbon dioxide reforming reaction includes Japanese Patent Application Laid-Open No. 08-231204 and Japanese Patent Laid-Open No. 2010-526759, a method for producing synthesis gas (including reforming of CO 2). 11-106770, etc. * This technology is incorporated in the present application, and carbon dioxide in exhaust gas is obtained by a known technique "inside the internal combustion engine of the present application. Reforming to the internal combustion fuel with raw heat ”is a great measure to reduce greenhouse gas emissions. Furthermore, the waste energy (approximately 70%, approximately 60% can be used for reforming). ), And the calorific value of the reforming raw material generated by the fuel generation is further increased.

Among the inventions of the present application, the carbon C of the synthesis gas generating material when the reforming means for reforming carbon dioxide is used may be carbon C using fossil fuel, and the carbon dioxide is reformed into synthesis gas. Therefore, CO ₂ emissions can be reduced by at least several tens of percent, and this is a greenhouse gas emission reduction measure.

The carbon dioxide reforming is a technique for extracting a mixed gas of hydrogen (H ₂ ) and carbon monoxide (CO) by bringing a hydrocarbon compound (for example, dimethyl ether) into contact with a catalyst together with a carbon dioxide and steam reformer (patent prior art). Document 2, JP-A-11-106770) is incorporated into the present application, and carbon dioxide is also used as a fuel for the internal combustion engine, thereby improving the fuel consumption and further reducing greenhouse gas emissions.

In the second invention, the water and carbon are reacted by the exhaust heat of the internal combustion engine to take out a mixed gas of hydrogen and carbon monoxide. For example, a water passage K is provided in the engine block 1 of the internal combustion engine. Thus, either water H ₂ O is converted to water vapor J or water vapor is converted to heated water vapor as a water vapor generating means, and {the pressurization pressure at this time is about 5 kg / cm ² }. An endothermic reaction channel S is provided in the exhaust pipe MS after the combustion stroke of the internal combustion engine, carbon (mainly carbon C from plants) is introduced into the endothermic reaction channel, and the steam or heated steam The carbon is reacted in an endothermic reaction channel to extract hydrogen H ₂ and carbon monoxide CO (synthesis gas), or a catalyst (ni is the mainstream) is opposed to the endothermic reaction channel. Means for taking out and reforming in the synthesis gas take-out path with heat at ° C. A livestock gas tank MT for stocking a mixed gas of hydrogen and carbon monoxide is provided, and the taken-out mixed gas of hydrogen and carbon monoxide is stored as livestock gas Or the fuel of the internal combustion engine that generates the mixed gas via a livestock gas tank. * The exhaust heat of the internal combustion engine is mainly generated by the internal combustion engine. Engine block The exhaust heat used to absorb heat in the water passage and turn the water into water vapor and the exhaust heat obtained by endothermic reaction of the heat in the exhaust gas in the exhaust gas pipe, the exhaust heat in the engine block and the exhaust gas pipe It is characterized in that it is mainly exhaust heat from two places of exhaust heat obtained by endothermic reaction of exhaust gas heat in the road {other large heat absorption sources include air conditioner refrigerant compression heat and There is exhaust gas after being absorbed by the various reforms}. What should be emphasized is that the heat that was cooled by the radiator (discarded using power) to prevent engine overheat as steam generating means It is to utilize.

The above is a configuration exemplifying the steam reforming of the second invention, but the known synthesis gas generation method includes the steam reforming method, the dry reforming method, the partial oxidation method, the autothermal reforming method, etc. Therefore, the above synthesis gas generation method can be adopted instead of the steam reforming method of the present application.

In view of the energy efficiency of internal combustion engines (about 30% for rotary engines and about 60% of waste (waste) heat available for syngas reaction), it is not enough to produce 100% of the required amount of fuel. In this case, supplementary means for supplementing from other places are provided as supplementary, and as an example of the supplementary means, the present application is provided with an auxiliary tank ST, and fuel in the auxiliary tank (bioethanol mainly made from plant carbon) Or, synthesis gas or hydrogen) is used as a supplementary fuel when it is not enough to produce 100% of the required amount of fuel.最終 Ultimately, the carbon is used as a measure to reduce greenhouse gas emissions by bringing it closer to 100% use of carbon from porcelain.

As an example of the second aspect of the invention, a composite fuel system is used in which a subtank fuel and a mixed gas generated in the internal combustion engine are switched and used, but hydrogen H which is a main fuel while the subtank fuel is being used. ₂ and carbon monoxide CO (synthetic gas) is produced, there is no place for producing livestock gas, and it is necessary to provide livestock gas means for livestock gas, and this application provides livestock gas tanks for livestock gas means Even when the sub-tank fuel is being used, hydrogen H ₂ and carbon monoxide CO, which are the main fuels, continue to be generated and continue to fill the livestock gas tank. An engine structure is provided with a fuel switching means that uses a sub-tank fuel when the synthesis gas is switched to use via a livestock gas tank with a fuel switching valve and the set lower limit of the livestock gas tank is reached. * The gas mixture produced by the internal combustion engine is used via the livestock gas tank because the composition of the gas mixture also changes depending on the raw materials and the temperature of the production site. The product gas is made uniform and the supply amount is controlled.

The synthesis gas reforming path of the third invention is taken out from any one or more of the reforming path, the take-out path or the synthesis gas production path generated in the first to second inventions, or taken from another place. A synthesis gas reforming path (for example, a proton conductive ceramic pipe reforming path) for reforming any one of a mixed gas (synthesis gas) of hydrogen (H ₂ ) and carbon monoxide (CO) is provided in the exhaust gas flow path; Steam in the mixed gas of hydrogen, carbon monoxide, and exhaust heat of the internal combustion engine {the exhaust heat of the internal combustion engine is exhaust heat in which water is converted into steam in a water passage in the engine block of the internal combustion engine} For example, the exhaust heat of the internal combustion engine (300 ° C. to 800 ° C.) again in the proton conductive ceramic tube (the exhaust heat of the internal combustion engine is exhaust heat obtained by absorbing the heat in the exhaust gas in the exhaust gas pipe) in a) at reacted dioxide and hydrogen (H ₂₎ Containing (CO ₂₎ were separately taken out, the hydrogen and carbon dioxide to provide a hydrogen slaughter gas tank and carbon dioxide slaughter gas tank to slaughter gas separately, and slaughter gas respectively, carbon dioxide, a starting material to take out the hydrogen As described above, the extracted hydrogen has a structure to be used as fuel for the internal combustion engine via a hydrogen livestock gas tank. * When exhaust gas temperature in the exhaust pipe is insufficient, an exhaust gas combustion section is provided upstream of the synthesis gas reforming path to compensate for the insufficient temperature in the unburned fuel gas or unburned carbon particles in the exhaust gas. It is also possible to reheat by introducing fuel and oxygen (air) as livestock gas.

The reforming temperature of the hydrocarbon compound (for example, dimethyl ether CH ₃ OCH ₃ ) reforming (first invention) described in the first invention is 200 to 500 ° C., preferably 250 to 450 ° C. The reforming temperature is 200 ° C. to 300 ° C., and the reforming temperature of steam reforming (second invention) is 700 ° C. to 1000 ° C., preferably 800 to 900 ° C., and steam reforming is performed upstream of the exhaust pipe. A reforming part of a hydrocarbon compound (for example, dimethyl ether CH ₃ OCH ₃ ) is provided downstream thereof, or a synthesis gas reforming path (reforming temperature is 300 ° C. to 800 ° C.) downstream of the steam reforming. ° C / third invention), or the above-mentioned synthesis gas reforming path is provided downstream of steam reforming, and a reforming section of a hydrocarbon compound (for example, dimethyl ether CH ₃ OCH ₃ ) is further provided downstream. It is preferable to take one of these forms.
Further combustion exhaust conduit into the catalyst (inexpensive high activity of the Ni-based catalyst mainstream) is an endothermic reaction at 300 ° C. vicinity of 200 ° C. provided a heat absorbing portion that is opposed to water between H _{2 O} and carbon C from the engine block of the internal combustion engine The synthesis gas generation reforming path for generating a mixed gas (synthesis gas) of hydrogen H ₂ and carbon monoxide CO is downstream of any one or more of the above first to third inventions. It is possible to create a synthesis gas generation path that uses exhaust gas heat after heat absorption in the reforming path as a reforming heat source to generate synthesis gas. This means that as the amount of heat absorption increases, more fuel generation means are incorporated. It is shown that.

In the hydrogen (H ₂ ) and carbon monoxide (CO) extraction channel, the reforming channel, and the syngas reforming channel, when it is desired to take a longer reaction time, or steam reforming or syngas is performed simultaneously. When it is desired to take at least one of the production path, carbon dioxide reforming, and synthesis gas reforming, the water passage K provided in the engine block (or rotary housing) of the engine is provided in the engine block 1. Or a plurality of exhaust lines from the engine block (for example, the same as the number of pistons, half the number of pistons, or the same number of pipes as the number of rotors) Or a structure in which one or a plurality of exhaust pipes from the engine block are further branched into a plurality of parts and sequentially switched to send exhaust). Is provided in the pipe downstream of the exhaust port after the engine combustion process with at least one of the two systems of pipes for further providing the water flow path K ′ to heat the carbon dioxide. A configuration in which at least one of the reforming paths is provided may be configured so that a mixed gas of hydrogen and carbon monoxide or a hydrogen gas and carbon dioxide are separately taken out.

Proton conductive ceramics have heat resistance according to the combustion temperature and are provided with continuous vents through which combustion gas can pass. Proton conductive ceramics such as strontium serate-based and zirconate-based belogskite oxide ceramics are hydrogen conductive ceramics. In terms of having an action of activating oxygen, it is particularly advantageous for taking out synthesis gas by reforming hydrogen and carbon dioxide separately.

The use of carbon dioxide or carbon as a raw material as a renewable energy source in equipment industries such as the manufacturing industry is a known technique.

The fourth aspect of the invention is that an internal combustion engine provided with one or more of hydrogen and carbon monoxide take-out path, reforming path, and synthesis gas reforming path is mounted on a transporting device and mounted on the transporting device. It takes the form of an engine, and the transport equipment includes a motorcycle, a munitions weapon vehicle, a munitions weapon ship, and the like.

According to a fifth aspect of the invention, the reforming heat source according to the first aspect of the invention is characterized in that the reforming heat source absorbs heat in the engine block through a water passage provided in the engine block. Having a structure that absorbs heat from a large engine block leads to the provision of several reforming paths.

According to a sixth aspect of the invention, an existing hydrogen rotary engine vehicle is employed in the internal combustion engine described in the fifth aspect of the invention, “the engine is operated under good fuel economy conditions (constant conditions) and power is generated with the rotational force. By storing the form of `` accumulating electricity in a capacitor and running an automobile using the electricity as a power source '' to the internal combustion engine, stable combustion heat can be obtained, and the endothermic reaction conditions are also stabilized. By making the present application “a structure in which the above engine is operated under conditions with good fuel efficiency, and power is generated by the rotational force and stored in a capacitor, and the electricity is used as a power source”, further improvement in fuel efficiency and greenhouse gases are achieved. It produces a great effect of reducing emissions.

* Driving conditions (for example, waiting for traffic lights, waiting for oncoming vehicles when turning right, waiting for crossing pedestrians when turning left or right at intersections, driving chocolate choco when in a busy state, driving on flat roads, overtaking & overtaking sudden acceleration・ The control mechanism and the control structure of the output of the internal combustion engine are simple and improved by following the change of the downhill traveling etc.
Furthermore, since the vehicle travels under certain conditions (conditions with good fuel consumption), there is an effect of improving the fuel consumption (Km / L).

When the storage amount of the capacitor of the seventh invention exceeds the set value, the driving of the internal combustion engine is stopped and the vehicle runs with electric power, and when the stored amount becomes less than the set value, the structure is driven by the internal combustion engine. If the driving condition is unnecessary, the engine is continuously operated under a certain condition (good fuel efficiency). Therefore, depending on the driving condition, the generated electricity required for driving the car becomes overcharged and the internal combustion engine generates power. Since the generated electricity is discarded, the engine can be turned off and the vehicle can be driven with the stored power to improve the fuel consumption.

In the eighth aspect of the invention, the internal combustion engine is provided with a charging / receiving plug, and is used as a charging means for storing electricity in the livestock generator. It is not necessary to install a lot of expensive batteries, and it is possible to receive and charge power in a place with a charging facility to increase the capacity of the storage facility of the internal combustion engine by several tens of percent. It will be a reduction measure.

A driving state that does not require power (waiting for traffic lights, waiting for oncoming vehicles when turning right, waiting for crossing pedestrians when turning left or right, choco choco driving in traffic jams, downhill driving, repulsive driving, etc.) In the above driving conditions, the engine is continuously operated under certain conditions (good fuel economy conditions), so depending on the driving conditions, the generated electricity necessary for driving the car becomes overcharged and the electricity generated by the internal combustion engine is discarded. Therefore, when the storage capacity of the livestock electricity reaches the upper limit set value, the engine is turned off and the vehicle runs with stored power. When the storage capacity of the battery reaches the lower limit set value, the engine is turned on and the engine runs with the engine. Can be improved.

In the ninth aspect of the present invention, when the vehicle is traveling on the downhill, the engine is set to 0FF (auxiliary equipment other than wheel driving is, for example, electricity), and a means for using the braking force of the brake for controlling the speed as power generation is further provided. Thus, by providing means for turning off the use of the driving power on the downhill and / or further using the braking force of the brake as power generation power, the fuel consumption is further improved and the greenhouse gas emission is reduced.

This is a repulsive driving on the flat road, but repulsive driving is about 1 minute with an accelerator operation (for example, 2200 revolutions) that is about 10% higher than the speed that the driver wants to travel, and the speed that you want to travel is 60 km. If it is / H, the rotational drive power connection of the engine is turned OFF at 70 Km / H (this will be about 1000 revolutions / the number of revolutions when idling, or the number of slow revolutions near zero in the case of electric drive). This is a traveling method that repeats the operation of turning on the rotational drive power connection of the engine when the speed reaches 60 km / H, about 3/4 of the time when the engine is increased by about 10%. Although it is a common-sense driving method in the transportation industry, it is possible to further improve fuel consumption and reduce greenhouse gas emissions by making this driving mode automatic control.
The shorter the unit of the ON / OFF cycle of the engine rotational driving force connection of the repulsive running, the smoother the speed becomes (for example, about 10 seconds).

Means for directly using the rotational force of the internal combustion engine of the tenth invention as power generation power of the power generator, or steam that has finished the role of turning the turbine of the thermal power generation and newly introduced plant carbon, Introduced into the endothermic reaction flow path and converted to endothermic reaction, the generated fuel (gas) can be used as a substitute for auxiliary fuel, and it can be used as a means to merge with the existing thermal power generation facility, or the thermal power An endothermic reaction facility may be provided in the exhaust gas line of the boiler of the power generation facility to cause endothermic reaction, and the generated fuel may be used as a means of using the livestock gas tank as the fuel for the power generation. .

In the case of power generation, a mixed gas of hydrogen and carbon monoxide or one or more of carbon dioxide or hydrogen can be handled by using products manufactured by other facilities (or transported in the compressed gas state by piping). In addition, ships and large automobiles are provided with a facility for producing a mixed gas of hydrogen (H ₂ ) and carbon monoxide (CO) in the vicinity of the internal combustion engine.

Eleventh invention, manufacturing industry that discards any one or more of heat, water vapor, carbon dioxide or hydrogen (eg steelmaking, iron forging, iron casting, aluminum production, dust incineration plant, petroleum Refined / petroleum product manufacturing / chemical factory, etc.) and / or equipment (for example, outdoor unit of air-conditioning Air Conditioner) and / or waste heat, steam or carbon dioxide Or any one or more of hydrogen is reformed by any one or more reforming technologies of reforming path, take-out path or synthesis gas reforming path, or the start of reforming The internal combustion engine is operated using the generated fuel as the fuel of the internal combustion engine, and “CO2” in the exhaust gas of the internal combustion engine is further converted into hydrogen and carbon monoxide by the reforming path means. Produced in the synthesis gas and the fuel of the internal combustion engine Drive Te is an internal combustion engine to the generator power of the rotational power as a power generator.

For example, in the rolling process of a steel mill, the decarburized crimson steel plate is passed through a number of rolling mills to form a steel plate roll of about 10 mm, but after the final rolling, a large amount of water is applied to make the red rolled plate dark. The plate is cooled, and a large amount of water applied at this time becomes steam, and a part of it is discarded, and the final rolled steel sheet roll is suspended from the ceiling crane in the steel sheet roll natural cooling cooling place. Are arranged in a sequential manner on a plurality of rows of roller conveyors that have been laid with the necessary clamping tool operating width. * The temperature of the steel sheet roll at this time is 700 ° to 900 °, and an endothermic reaction section is provided between the roller conveyors to generate an endothermic reaction. Power generation is a power reduction measure and a greenhouse gas emission reduction measure.

The livestock gas tank of the twelfth aspect of the invention and the thirteenth aspect of the invention {the tank does not require a 35 MPa high-pressure hydrogen gas storage tank, and is necessary for operating at least about 10 minutes with the gas generated by the internal combustion engine. This is a damage prevention means for preventing damage to the tank in which the internal combustion engine can be operated (if the switching loss is ignored) if it is a tank capable of stocking fresh fuel. A shock-absorbing material HPE such as foamed polyethylene and boron fiber reinforced plastic is fixed and held on the upper part of the vehicle as a single package, and fixed and fixed on the upper part of the vehicle with the fixing holder MT1 for fixing and holding. The tank separating means is fixed to the fixture MT5, and when the impact is applied to the fixture MT5, the V-shaped notch MT6 breaks due to concentrated stress, and the package of the impact cushioning material T3 (in which the tank support MT2 is integrated) is disengaged from the fixture MT5 (it is not completely disengaged but is locked to the fixture MT5 or the like with a linear body or the like). (This is a preferable form because it is a measure for avoiding the secondary damage in which the inclusion body MT3 completely comes off.) It is an exemplary structure), and the tank is removed from the tank preventive means for preventing the tank damage or from the tank installation portion of the car at the time of collision. One or both of tank separation means for separation are provided, and further, non-stationary equipment of the livestock gas means (for example, an automobile) livestock gas tank The livestock gas tank is mounted on the upper body of the car, mounted on the chassis of the truck, or attached to the non-stationary equipment. Although it is preferable, in the case of stationary equipment (for example, a power plant), it must be composed of the structure and material within the safety standards (in Japan, the registration of JIS B 8265 has been completed and there is ISO 16528 internationally) Therefore, the livestock gas tanks for non-stationary equipment and livestock gas tanks for stationary equipment (eg chemical factories) must each be composed of those within the safety standards or at least having elements that can change the safety standards. Although the non-stationary equipment (for example, automobile) livestock gas tank and the livestock gas tank of the stationary equipment (for example, chemical factory) have the same function of storing gas, their structures (standards) are completely different.

Fourteenth invention, for example, sodium hydrogen carbonate (NaHCO ₃ ) is processed by exhaust heat of the internal combustion engine and pyrolyzed to produce hydrogen (H ₂ ) and sodium carbonate (Na ₂ CO ₃ ), and the sodium carbonate is taken out It is sold as a product and is configured to use hydrogen as a fuel for an internal combustion engine via a livestock gas tank. Whether it is a reforming path, a take-out path, a synthesis gas generation path, or a synthesis gas reforming path due to the exhaust heat of the internal combustion engine Of these reforming technologies, the sodium hydrogen carbonate is an example as long as it is a product that is reformed by one or more reforming technologies to extract the fuel, and is not limited to sodium hydrogen carbonate.

The combustion exhaust gas of the internal combustion engine of the fifteenth aspect of the present invention is an exhaust mainly composed of water and nitrogen when hydrogen gas is combusted, and is composed mainly of water, carbon dioxide and nitrogen when combusting hydrogen and carbon monoxide. Exhaust gas with hydrogen, carbon monoxide modified from carbon dioxide in the exhaust gas, and exhaust gas mainly composed of water, carbon dioxide and nitrogen,
Regardless of which fuel is used, the water is discharged in the form of water vapor, and the structure is such that the water of the reforming starting material is warmed from the water vapor by further heat absorption means, and the water is removed from the water vapor in the exhaust gas and filtered. For use as water of the reforming starting material via the filtering means, the heat absorption means from the water vapor, for example, is provided with a water storage tank in the downstream portion of the exhaust pipe and passes the exhaust pipe into the water of the storage tank The water recovery means is characterized in that the water in the water tank absorbs heat, the water in the water tank becomes warm water, and the water vapor in the exhaust pipe becomes water, and the water is recovered. Since the fuel is reformed into fuel, a considerable amount of water is required, but if the loading capacity is increased, the fuel for transporting the loaded water (weight) is required, so water is recovered and recycled. If this is done, the load can be reduced, and the water in the water tank Since Oru as means) can recycling water introduced the water from the inlet port of the water of the engine block, this will contribute to the reduction and emission reduction greenhouse gases. * In addition a cooling water sea water of an internal combustion engine such as a ship that travels sea level, either by providing a K ^S in addition to the water passage K &K'provided herein in the engine block said K'or K ^S Seawater is separated into fresh water by the exhaust heat of the internal combustion engine in the water passage, and as a seawater separation water vapor generating means for extracting water vapor from the sea water used as the water vapor of the reforming means of the present application, the remaining sea water contains mineral components. It can also be used as a salt separation and recovery means for producing and taking out the contained salt.

A sixteenth aspect of the invention is a small-scale carbon production apparatus for producing plant carbon as described in the first to fourth aspects of the invention, and heats wood and the like (plant raw material) in an environment free of oxygen to carbonize. Carbonization chamber CS to be fired, combustion chamber FC for burning plant raw materials such as wood for heating the carbonization chamber, exhaust gas vent of combustion chamber FC, and pipe J of water vapor generating means for converting water H ₂ O into water vapor J Is provided along the inner wall of the carbonization chamber, and the structure is such that the steam generated by the steam generation means and the gas C4 generated in the carbonization process in the carbonization chamber are introduced into the combustion chamber to serve as fuel for heating the carbonization chamber. And / or the reforming means technique of the first invention is provided in the exhaust part (for example, a chimney) of the exhaust gas pipe, and as an example, the reforming substance is dimethyl ether, and the reforming part is opposed to the catalyst. Either dimethyl ether with water vapor or carbon dioxide Towards one of either a small carbon maker provided in either one of a configuration of a fuel small carbonization device is brought into contact with the catalyst.

In the seventeenth aspect of the invention, the carbonization chamber CS section is configured to vent the partition walls between the carbonization chamber CS and the combustion chamber FC in the configuration of the small-scale carbon production apparatus, and the carbonization chamber CS section separates carbon dioxide from the steam J generation section and exhaust gas A heater using a fossil fuel such as coal by providing a separation unit that further provides the reforming means technology of the first invention in the discharge unit (for example, a chimney) of the exhaust gas pipe (For example, coal stoves) are used as heaters to reduce carbon dioxide emissions. * This is because many cold districts use coal stoves and ignore carbon dioxide emissions from coal combustion. It is those that can not, the first of the present invention and of the greatest challenges configuration structure applying the present application of the second invention to deal with global warming "CO _2" one of emission reductions become measures Means.

In the combination of the present invention, the carbon C of the synthesis gas generating material when the reforming means for reforming carbon dioxide is used may be fossil fuel use (for example, coal), which is a greenhouse gas emission reduction measure. is there.

An endothermic reaction flow path is provided in the engine block of the internal combustion engine, and water H ₂ O and carbon C are reacted with the exhaust heat of the internal combustion engine to take out a mixed gas of hydrogen H ₂ and carbon monoxide CO. It is an internal combustion engine that uses a mixed gas of carbon monoxide and fuel, but any manufacturer thinks that synthetic gas can be used as an alternative fuel to gasoline, light oil, heavy oil, etc., but hydrogen also Carbon monoxide is also very dangerous (explosive and toxic). Therefore, liquefied transport means (portability). The ratio of the volume of the liquefied gas to the weight of the container that satisfies safety standards is poor. I suspect that there was an explosion problem caused by the wreck, and I couldn't get it.
The means of the present application for solving this problem (the means of the second invention) is as follows: * Replenish the energy loss during the fuel generation process, instead of filling the tank with the consumed fuel to cover all the fuel required for running. A sub-tank is provided, and the fuel in the sub-tank is one of petroleum liquefied gas (including natural gas), gasoline, hydrocarbon-based fossil fuel bioethanol, etc., or synthetic gas as supplementary sub-fuel for energy loss. A combined fuel replenishment structure that uses syngas to produce livestock gas tanks and adopts livestock gas tanks (configuration that can respond to accidents such as the location of livestock gas tanks taking into account the stored gas pressure and the car being severely damaged) The fact that it is provided as a structural means) is a major point that made the present application an “implementable plan”. (See Figures 1 and 2)

A certain amount of the synthesis gas produced in the livestock gas tank is stored (in the state of compressed gas), and while it is stored, butane gas, gasoline, (including hydrocarbon fossil fuel) methane gas, bioethanol, etc., or hydrogen, synthesis Any of gas, reformed gas from plants, methane gas from plants, bioethanol of bioethanol, etc. is used in the auxiliary fuel tank storage gas. When using the synthetic gas in the livestock gas tank while generating synthesis gas, and when the tank capacity is close to “0”, switch to using the auxiliary fuel tank. Is also included.

An example of a known technique for converting carbon dioxide into hydrogen, carbon monoxide, etc. in the presence of a catalyst is described in Patent Document 2 and JP-A-11-106770. Has been invented of a method for producing synthesis gas by reacting with steam and / or carbon dioxide in the presence of the catalyst and a catalyst suitable for the method, and this technology is used as a technology for reforming carbon dioxide of the present application into fuel. I use it.

Japanese Patent Application Laid-Open No. 2007-177684, a carbon dioxide recovery device for a vehicle, and a vehicle equipped with the same describes that carbon dioxide is absorbed by a carbon dioxide absorber and carbon dioxide is recovered.

The main sources of greenhouse gas emissions are emissions from internal combustion engines and thermal power generation boilers, which account for about 82% of Japan's power generation (2012 Electricity Federation statistics). And emissions from thermal power boilers account for ¼ of global emissions.

The amount of CO ₂ released when 1 gallon of gasoline is burned is about 9 Kg combined with emissions from the car engine and emissions from the gasoline production process.

Therefore, in order to shift the consumption of carbon C of fossil fuels to carbon C of plants and achieve a 25% reduction in greenhouse gas CO ₂ emissions at an early stage, the internal combustion engine of the greenhouse gas emission reduction measure of the present application should be It is necessary to implement such measures and to make the procurement cost of carbon C, which mainly consists of fuel plants, the same as the procurement cost from fossil fuels.

The production of carbon C as fuel changes when carbonized organic material is heated while shutting off the flow of air and oxygen, and changes to a material rich in black carbon. This process is called carbonization, and charcoal produces this carbonization. This is a good example of a product, and the product is an aggregate mainly composed of amorphous oxygen, etc., which is mostly porous, has a very large surface area, undergoes dehydration and dehydrogenation reactions by heating, and is condensed polycyclic aromatic. This is called carbonization, in which a compound is formed and a network structure is formed.

The technology for making solid carbon C (plant raw material C) from wood (including old wood and sawdust) into nanoparticles is not yet a new technology because it has already been broadcast on TV, but it does not make nanoparticles fine. Even micronization (about 100 microns) can be handled as the carbon C of claim 2 of the present invention.
If the solid carbon C is pulverized into fine particles, the surface area where the reaction takes place is increased. Therefore, the finer the particles, the more efficient the synthesis gas generation.
It can also be handled by adding water to the carbon C to form an emulsion fuel or gel.
Furthermore, the above-mentioned wood or the like (plant raw material) is heated in an environment where oxygen does not enter, and carbon C gas can be obtained in the carbonization step.

It is a cycle that absorbs heat in the engine block to convert water into water vapor → endothermic reaction in the exhaust pipe → carbon monoxide and hydrogen synthesis gas or hydrogen and use it as fuel for the engine. As a matter of fact, the livestock gas tank has a large volume, low pressure accumulation, a tank that can be built, where the vehicle is located, and what kind of structure it should be so that the livestock gas tank will not burst even in the event of a car wreck. It was possible.
* The above-mentioned proposed matter was solved with the following structure.
1. The place where the synthesis gas tank is placed is located at the upper part of the car body or at the chassis part of the car, which is provided at the upper part of the car body, even if the car falls from the cliff, Even in an accident where sandwiches are crushed between the trucks, the livestock gas tank requires a tank that does not explode, but the target hydrogen that can be driven by a contractor in a cylinder that can be mounted on the vehicle is 500Km and 20MPa at 5Kg of hydrogen. With the pressure of 375L, the volume of the container is 375L, and the hydrogen 74L / 35MPa installed in Mazda (company name) Premasi Hydrogen RE hybrid vehicle can run only 123Km with full tank filling, so about 500Km is about to run Four times as many 375L hydrogen tanks are required, but to supply 375L / 35MPa of hydrogen in a 74L container, about 1 0MPa filling can be container in compression is required it is difficult with current technology.
Therefore, it was planned to generate synthesis gas in a mounted internal combustion engine. However, in a pressurized pump with a mounted structure, if the compression pressure is increased, more power is consumed for the pressurized pump. At the start, the gas was accumulated with equipment equivalent to an accumulator of hydraulic equipment, but the car fell from the cliff due to an accident on the highway where the livestock gas equipment should be installed. If the accident is such that the car is flipped upside down or the passenger car is sandwiched between large trucks and crushed in a sandwich, the structure must be such that an explosion can be avoided when such an accident occurs. I gave up on board.
If you are searching for related documents on the Internet and searching for prior literature for planning other projects using synthetic resin, the following foamed polyethylene, (the above-mentioned member has anti-bullet properties and is used for military weapons, (As an example, polyethylene fired polyethylene is fixed to the outer surface of an army water hoat for army movement, and when it is sniped with a rifle etc., the bullet has a bullet-proof property that does not allow a hole to be made in the rubber hote) Can be found, and if this was used, it was able to solve even the place where it did not explode even if the accident occurred. However, the problem was the location of the last remaining tank.
While considering the eco-driving method filed last year and thinking about what to do with resin to reduce the weight of the car, when considering the roof of a passenger car, the livestock gas tank of the present application that had been neglected was used for the roof of the car The structure of this livestock gas tank is the key point of the present application. (See Figure 1A and Figure 2)
2. As shown in FIG. 2, the outer surface of the livestock gas tank is formed by fixing, coating, or other synthetic resin material in a form covering the tank portion with a poron fiber reinforced plastic or foamed polyethylene. In this way, the tank is separated from the car body when a shock is applied to the car that falls or is severely damaged. (It is preferable to provide a locking structure that does not jump too far.)
3. As an example of the separation structure of the tank inlet / outlet pipe from the vehicle body, the solenoid valve contact configuration is ON when energized. When the solenoid valve sequence circuit is turned off when not energized, and the synthetic gas tank is subjected to an impact force flying from the body of the car, the gas inlet / outlet pipe of the tank may come off (or be damaged). The gas pipeline from the tank is closed. (See Figure 2.H)
4). As for the problem of compression pressure of livestock gas, if the structure of Mazda (Company Name) Premacy Hydrogen RE hybrid vehicle that uses auxiliary fuel and the internal combustion engine only generates electricity is used, By combining the sixth to ninth inventions and the fifteenth invention in addition to the reforming technology, even if no auxiliary fuel is used, only synthesis gas or only hydrogen, or switching between synthesis gas and hydrogen can be used. The preferred embodiment and the stored gas pressure can be accommodated with a low compression pressure as described in the next paragraph.

In order to cover the fuel necessary for running 500 km with gasoline with hydrogen (synthetic gas), 5 kg of hydrogen (equivalent to 56,000 L of hydrogen) and (10 g / Km = hydrogen of 11.2 L). Therefore, the capacity of a livestock gas tank for fuel (hydrogen, synthesis gas, carbon dioxide) required for about 10km travel is a livestock gas tank capable of livestock gas of 11.2L * 10 = 112L (normal pressure) if the fuel switching loss is ignored. It will be good if there is. Therefore, it can be designed freely as long as it is within the scope of the above law and the relationship between the tank manufacturing cost and installation space, the switching cycle to be set, the livestock gas pressure to be set.

Generated exhaust gas In configuration C to produce a synthesis gas CO + H ₂ by exhaust heat of the E _X, produced synthesis gas is to slaughter gas in the synthesis gas storage tank (slaughtering gas tank) MT, in order to compensate for the shortage of the generation fuel The sub tank ST is provided to store the sub fuel, and the sub tank fuel and the synthetic gas stored in the livestock gas tank are switched by the switching valve CB and supplied to the injector E _C H ₂ through the fuel supply line 5. Further, it is a schematic configuration diagram of an internal combustion engine having a configuration with a plug P for forced ignition.
In addition to the above-described configuration, the exhaust pipe is branched into a plurality of parts, and the exhaust pipe is used as a reforming section to confront the catalyst. A hydrocarbon compound and carbon dioxide are introduced upstream of the reforming section to The structure Ca can be brought into contact with the catalyst together with water vapor, or the reforming path can be provided in the exhaust pipe to introduce carbon dioxide and a hydrocarbon compound (for example, dimethyl ether CH ₃ OCH ₃ ). A synthetic gas in which a synthetic gas of hydrogen and carbon monoxide is generated by contacting with a catalyst in a gas flow path and reacting with exhaust heat in the exhaust gas, and the modified synthetic gas is further provided downstream It is the schematic block diagram which showed that it can also be made into the structure Cc which introduce | transduces into a reforming path and reacts by exhaust heat again, and takes out hydrogen and a carbon dioxide.

As an example, this figure shows a synthetic gas tank having four cylindrical MTBs, and a single package of impact shock absorbers such as polyethylene foam, boron fiber reinforced plastic, and the like. In the state where the vehicle is fixedly held on the upper part of the vehicle, and is fixed to the fixture MT5 that is fixedly fixed to the upper part of the vehicle with the fixed holding fixture MT1. The V-shaped notch MT6 breaks due to concentrated stress, and the shock absorbing material inclusion MT3 (for example, the tank support MT2 is integrated) is detached from the fixture MT5 (completely disengages). In this case, it is preferable to use a structure that is locked to the fixing device MT5 or the like with a thread body or the like because this is a measure for avoiding secondary damage in which the inclusion body MT3 of the shock-absorbing material completely comes off.

As an example, when a collision or falling force is applied to the tank, a holding structure in the event of an accident is provided, and a structure (part of which is preferably connected to the car) is provided. The tank that flies off from the vehicle is made of foamed polyethylene, boron fiber reinforced plastic, impact buffering material (HTP), etc., which is provided on the outer surface of the tank and fixed to the entire surface, and absorbs or diffuses impact force. So it does not explode. The foamed polyethylene, boron fiber reinforced plastic, and shock-absorbing materials that are fixed to the entire surface of the coating or the entire surface may not be expensive at this time, but they are produced almost 20 million units / year (by the entire Japanese automaker). The cost is reduced due to the effect.

It is a schematic diagram of a structure in which gas is stored in a tank via a contact circuit) and introduced into the fuel switching valve Cb of the engine. If the force is applied to the tank and the gas storage tank comes off, the electrical wiring will be disconnected and the electromagnetic valve will be turned off so that the gas in the tank will not leak.

As long as the HPE body has a function of separating to the upper part, it does not stick to metal, synthetic resin, other, material and shape.
It is preferable to provide a carbon dioxide livestock gas tank and a hydrogen livestock gas tank in the structure of the livestock gas tank.

Although the above-mentioned supplement, wherein the steam reforming (synthesis gas taking-out passage or synthesis gas production passage) synthesis gas produced in the schematic material weight of CO and H _2: a mixture of 1. Since the gas volume is proportional to the amount of the substance, the amount of carbon monoxide = the amount of hydrogen and the gas has a volume of 22.4 L / mol in the standard state. (Transfer efficiency of liquid hydrogen: high pressure hydrogen = 6: 1) Hydrogen is 39 g per liter (weight in tank of 700 atm).

FIG. 5 is a schematic view showing a hydrogen rotary engine disclosed in Japanese Patent Application Laid-Open No. 2007-2111608.

FIG. 6 is a diagram showing a main configuration of an electronically controlled injection structure of a hydrogen rotary engine, and the electronically controlled injection valve needs to inject a large capacity of 2300 NL / min in order to obtain an output of 100 KW, for example.

According to the Kyoto Protocol, carbon dioxide CO ₂ produced by the combustion of plant carbon C is consumed by plant carbon assimilation, so it is a plus or minus zero and is not counted as CO ₂ emissions. Therefore, in order to shift the carbon consumption of fossil fuels to plant carbon and achieve a 25% reduction in greenhouse gas CO ₂ emissions at an early stage, it is best to realize the above-mentioned synthesis gas generation cycle plan. think. (According to 2010 data from the Ministry of the Environment, greenhouse gas CO ₂ emits 30.3 billion tons worldwide, Japan is 3.8%)

The day when solar power generation (system using solar power generation panels, condensing sunlight, generating steam with heat → power generation) will become the mainstream of future power generation is not far away. However, solar power generation is not possible 24 hours full-time power generation at night, rain, and cloudy, and if it is installed on a large scale, it will be quite remote from the power usage area, so it will install new substation and transmission equipment The disadvantage is that large-capacity power storage equipment is necessary to cover only with solar power generation, and if it is a place with a good sunshine rate (for example, a desert with low annual rainfall is the leading candidate), a large amount of power transmission / reception equipment is required. (There is superconductivity invented by Japan in the above-mentioned large-capacity power storage equipment, large-scale power transmission / reception equipment, the experimental plant is already in trial operation, and the international standard of 1,100,000V was also established in 2008. Although it has just gained international approval, the gap with the estimated cost is a problem).
Therefore, if the internal combustion engine power generation of the present invention that can be operated for a short time other than the solar power generation time is used in combination with the fuel production mechanism of the present invention, it can be said that the reduction of greenhouse gas CO ₂ emission can be achieved earlier. .

The feasibility of reducing the procurement cost of carbon C used as a fuel is the success or failure of the practical application of the second invention of the present application. In carbon production, when carbonized organic substances are heated with the air and oxygen flow blocked, they turn into black carbon-rich substances.This process is called carbonization, and charcoal is a good example of this carbonization product. The resulting product is an aggregate mainly composed of amorphous oxygen and the like, and is mostly porous and has a very large surface area. Heating causes dehydration and dehydrogenation reaction to produce a condensed polycyclic aromatic compound, which further forms a network structure, which is called carbonization. *

FIG. 10 is an assumed schematic diagram of the above-described small-scale carbonization apparatus. Carbonization plants suitable for the carbon material of the present application are placed in the carbon production chamber CS, and the combustion chamber FC serving as a pot door is approximately half carbonized of the carbon material of the present application. By burning the timber plant and accumulating it in the accumulation area in the form of carbon C, it is possible to reduce the transportation cost much more than the transportation with branch wood, and the plant in an environment where oxygen does not enter In the combustion chamber FC that heats the raw material (wood, etc.) into the carbonization chamber CS for carbonization and burns the fuel for heating (plant raw materials such as wood or other combustion materials) for heating the carbonization chamber An exhaust gas exhaust line Ex of the combustion chamber FC and a water vapor generating means pipe J for converting water H ₂ O introduced from the water tank into water vapor are provided on the inner wall of the carbonization chamber. The generated gas C4 is burned together with water vapor in the introduction pipe C4. It is a structural structure that is introduced into the firing chamber to heat the carbonization chamber,

The reforming part (CO ₂ reforming) having the structure described in the paragraph of the first invention is provided in the discharge part (for example, a chimney) of the exhaust gas pipe, and the reforming substance is dimethyl ether as an example. If the reforming section where the catalyst is opposed is reacted with dimethyl ether, either steam or carbon dioxide, to make fuel for small-scale carbonization equipment, the fuel consumed for carbonization is further reduced, and the greenhouse is reduced. Reduction of effect gas emissions.
Furthermore, by using a reforming section (CO ₂ reforming), fossil fuels such as coal can be used, and wood or the like used as fuel can be used as a starting material for reforming to C as a plant raw material.
As an example, the catalyst can be used in combination with other metals or compounds in addition to iron-based metals and / or compounds. Examples of other metals or compounds include zinc, nickel, chromium, manganese, tin, cerium, and lanthanum. And these compounds, other metals or compounds.

The synthesis gas described above is not limited to hydrogen and carbon monoxide. The synthesis gas represents a main component, and includes, for example, unburned carbon, carbon dioxide, moisture, and other gases and impurities present in the atmosphere. This includes cases where

The procurement cost of carbon (plant raw material C) is currently higher than that of natural gas (methane, butane, etc.), coal, and petroleum fossil fuels. Until it can be obtained, or the law for strengthening greenhouse gas CO ₂ emission regulations is made, the procurement of carbon will be done with natural gas or directly with natural gas as fuel, and the desire of the whole society will increase and the procurement of carbon There is a way to switch when the cost can be paid, however, I think that the speed of progress in chemical technology is progressing in proportion to "needs", so renewable carbon C that will be the main raw material of this application I am confident that the procurement technology will evolve at an accelerated pace if the procurement needs are high. The carbon used in the internal combustion engine cycle of the present application is the cheapest to use “coal” as powder for the time being, so the fossil fuel will be used until the renewable carbon C procurement system is complete. It will take the form of shifting to a carbon C procurement system that can be sequentially regenerated.

The amount of purchase of greenhouse gas CO ₂ emission allowances in Japan is estimated to be about 1 trillions of billions of yen. If this purchase amount is used as part of the carbon procurement cost, the time of realization of the present invention will be explained. Will be faster.
* If transported from a chemical factory, steel factory, aluminum factory, dust incineration plant, oil refinery factory, etc., with a mixed gas of hydrogen and carbon monoxide, carbon dioxide, hydrogen, etc. in a pipeline, it will be much more than transport by transportation equipment. The transportation cost can be reduced.
Each US and European country has a hydrogen transport pipeline of thousands of kilometers, and should be realized early with the support of the government in order to survive the world as a competitor.

The power generation equipment powered by the internal combustion engine of the present application is a relatively small-scale power generation equipment (if the power generator is assumed to have an output machine of 1000 KW / H as 1 unit / unit, 1 unit to several hundred units Because it can be a decentralized power generation system with self-sufficiency in units of mass such as remote islands, mountainous remote areas, industrial parks, submarine transmission cables and power demand It is possible to drastically reduce power transmission facilities, power transformation facilities, and power reception facilities that respond to changes in power consumption. Furthermore, the existing thermal power and nuclear power plants need to be adjacent to the water source, but the location condition of the power generation facility of the present application does not need to be adjacent to the water source and has the advantage that it can be installed as close as possible to the power demand area.

When methanol is used as a fuel for an internal combustion engine, methanol is originally synthesized from hydrogen and carbon monoxide at a high pressure advantageous from chemical equilibrium. Therefore, it is most efficient in terms of energy to use it in the form of synthesis gas of hydrogen and carbon monoxide, rather than converting it to hydrogen.

Although transportation of compressed hydrogen and liquid hydrogen is carried out, in order to compensate for the problem that the volume storage density of hydrogen gas is small, hydrogen is transported as compressed hydrogen under a pressure of 14.7 to 19.6 MPa. Mo steel hydrogen container is heavy. For example, a trailer vehicle that transports 100 kg of hydrogen requires 7 tons of hydrogen container. To reduce the cost of transporting compressed hydrogen, aluminum alloy liners and high-density polyethylene liners are used. It is necessary to make a tank reinforced with glass fiber or carbon fiber,
Under current regulations (in Japan, registration of JIS B 8265 has been completed and internationally there is ISO 16528) CFRP for transportation (tank with high-density polyethylene liner reinforced with glass fiber or carbon fiber on the entire surface) ) Since the container has a pressure of up to a capacity of 35 MPa, it is necessary to relax regulations in order to utilize the container. (Japan Industrial Gas Association, hydrogen gas container standards)

On the other hand, liquid hydrogen has a volume storage density that is more than 800 times that of hydrogen gas, and tank trucks or insulated containers are used. However, liquid hydrogen requires energy for liquefaction, and has a boiling point of -253 ° C and evaporation loss. There are disadvantages that occur.

The internal combustion engine of the present invention uses synthesis gas or hydrogen as a fuel, and the synthesis gas or hydrogen or carbon dioxide is a pipe supply in a transporting device, and the synthesis gas or hydrogen or carbon dioxide produced in the internal combustion engine. The accumulated pressure of the livestock gas tank for stocking carbon does not need to be a 35 MPa livestock gas tank of compressed gas mounted on the existing hydrogen engine car, and may be about 1/40, and the pressure can be lowered. The energy used for the partial pressurization pump does not need to be used, and the structure of the gas storage tank can be made to be at most several MPa within the current regulations.

Pipeline transportation is optimal for steady mass transportation of hydrogen, and the synthesis gas of this application is similar to hydrogen in Europe and the United States. Pipe transportation is the best means.
As the pipe material of the hydrogen pipeline, in the current advanced technology, if it is a sour-resistant material with a reduced amount of vanadium and a small amount of nickel or chromium, compared with ordinary line pipe steel, it can be used in a normal transportation environment. It is said that the cost can be increased to 10% or less.

The rotary engine vehicle using hydrogen as a fuel is a Mazda Premacy Hydrogen RE hybrid vehicle with a structure that allows you to choose between running on hydrogen and running on gasoline. High-pressure hydrogen fuel tank (35MPa, 74L) The car is equipped with a gasoline tank, which generates electricity by rotating a hydrogen (or gasoline) rotary engine and stores it in a lithium-ion battery. The drive of the wheels is electricity stored in the battery. Is a place where the engine is operated under good fuel efficiency, and the vehicle speed fluctuations depending on the running state of the car are controlled by electric control. The disadvantage is that the mileage when the high-pressure hydrogen fuel tank is full is as short as 100 km. Hydrogen transportation means (assuming transportation by car) has a poor ratio of hydrogen loading weight to tank weight. That La development does not proceed and hydrogen production and transportation costs is a high point, and the like.

The Mazda (name of company) hydrogen rotary engine generates electricity using hydrogen H ₂ as fuel, and the motor is rotated by the electricity. Therefore, the power generation component can be used as a power generator, and the power generation configuration as the power generator. The portion is applied to the internal combustion engine of the present application.

The carbon sources mentioned above are dead trees that have been eaten by pests such as thinning and pine wilt, and rice husks and husks generated in Japanese rice farming are discarded. Cultivating kenaf (Hibiscus cannabinus L) in vacant land such as fallow land, which can be mixed with carbon (C) in mixed gas production plants at a rate of 20% oil to the plant However, it goes without saying that cultivating corn, sugarcane, etc. in vacant areas such as fallow land can also be used as biofuel for plants, but most of the rice fields have agricultural waterways, and Since it has been fertilized for many years, for example, cultivating taro, wheat, and actually edible waste as biofuel or plant carbon of the plant and wheat straw as carbon of the plant. There is also a way of saying to policies that compensate for the difference between the revenue obtained by the income and rice obtained Rakara, it is more construction waste and lumber residual materials and Hitoshi Furuki also.

Various embodiments that can be easily conceived from the events described in the present specification and claims are included in the present invention as long as they do not depart from the scope of the claims.

This project is partly undeveloped, but the internal combustion engine of the present application can be implemented, people who are engaged in manufacturing these methods and components, then those who use those methods, internal combustion engines, Furthermore, it can be used for those industries that spread to people in industries related to them.より Above all, creating a cycle that makes the best use of the country's resources will create a soil that will create a total of 100 years in Japan, leading to the development of these industries.
