A. In the method of obtaining hydrogen by thermally decomposing 100% water, water has a strong bond between hydrogen and oxygen, so theoretically, it does not decompose into hydrogen and oxygen unless a temperature of 3,000 ° C to 5,000 ° C is given. It is said. In the method of obtaining hydrogen by thermally decomposing water at a temperature of 3,000 ° C. or higher, it is not possible to obtain a substantial method for obtaining a high temperature of 3,000 ° C. or higher, and such a high-temperature space from outside Hydrogen generation by thermal decomposition of water because there are many problems such as inability to make equipment to maintain low cost and inconceivable means to supply water continuously in a high temperature space Has not been realized.

b. Since the IS method shown in Patent Document 1 requires high heat of about 900 ° C., a high temperature gas furnace or the like must be used as a heat source. This high temperature gas furnace has a high manufacturing cost, and hydrogen is manufactured through three steps, and the cost for manufacturing hydrogen is very high.

c. In the method for decomposing water shown in Patent Document 2, hydrogen is produced by reacting metallic zinc and magnetite with water vapor at 600 ° C., and a heating means for producing 600 ° C. water vapor must be provided.

d. In the method for producing hydrogen shown in Patent Document 3, non-freezing water having a pH of 4 to 10 is used as water, and hydrogen is generated even at 0 ° C. or lower. In Patent Document 3, hydrogen is generated by a reaction between aluminum and water. However, since the reaction is performed at a low temperature of 0 ° C. or less, a large amount of hydrogen cannot be generated at a low temperature, and hydrogen is generated with high economic efficiency. It cannot be generated.

The present invention uses a method for producing hydrogen capable of producing hydrogen by bringing reformed water into contact with aluminum, and uses the reaction heat at low temperature by bringing reformed water into contact with aluminum. Then, it aims at providing the hydrogen production apparatus for producing hydrogen efficiently with low energy, using the energy from the outside as much as possible.

The method for producing hydrogen according to the present invention is based on the standards of tap water as drinking water in Japan, filtered with a water purifier, purified with RO membrane, etc., water added with minerals, soft water, etc. Use fresh water. After that, natural ore or artificial ore, or what is produced by passing through natural ore and artificial ore is used as modified water, and the modified water and aluminum are placed in a reaction vessel and contacted in the reaction vessel. In this state, the temperature in the reaction vessel is 25 ° C. or higher and lower than the boiling point of the reformed water, whereby the reformed water and aluminum are reacted to generate hydrogen.
In the present invention, reformed water is produced by generating hydrogen by making aluminum powder or ingot-like, granular, powder of any shape, and setting the temperature in the reaction vessel to 25 ° C. or higher and lower than the boiling point of the reformed water. Alkaline (alkaline modified water). Then, by supplying new aluminum powder or ingot-like, granular, powder of any shape to alkaline special water in the reaction vessel, the temperature in the reaction vessel can be reduced to 25 without heating by heating means. It is characterized in that hydrogen is generated while being kept at a temperature of not lower than the boiling point and below the boiling point of the reformed water. The present invention is also characterized in that when the temperature in the reaction vessel is 25 ° C. or higher and lower than 80 ° C., the temperature in the reaction vessel is continuously increased by heating means and electrolysis. The present invention provides natural ores for producing modified water, including pyrite, marcasite, cinnabar, galena, porphyry, halogenated minerals, fluorite, cryolite, tourmaline, obsidian, magnesium, calcite, Use urexite (TV stone), Coleman stone, borax, howlite, gypsum, barite, celestite, phosphorite uranium, carnotite, bronze stone, black sand goldstone, barley stone, quartz, etc. 1 to 5 mm, 5 to 10 mm, 10 to 20 mm, 20 to 40 mm, and 30 to 50 mm. Moreover, terahertz ore etc. are mentioned as an artificial ore for producing | generating the modified water. In the case of using an artificial ore, at least one kind of metal such as aluminum, stainless steel, and silver is mixed as a substance other than the artificial ore. In addition to natural ores, it is also effective to add minerals that can be extracted from natural ores. For example, minerals extracted from granite are used. Examples of added mineral components and individual substances to be added include calcium, phosphorus, silicon, magnesium, sodium, selenium, zinc, vanadium, germanium, nickel, manganese, molybdenum, copper, tungsten, cobalt, lithium, barium, iron , Potassium, aluminum, rubidium, titanium and the like. The present invention is characterized in that 3 parts by weight or more, preferably 15 parts by weight or more of aluminum is blended with 100 parts by weight of the modified water. Furthermore, the present invention is characterized in that the weight part of the aluminum is 10≡40 parts by weight or more.

The present invention adds an alkaline substance to the modified water. A typical example is sodium hydroxide. A sodium hydroxide aqueous solution to which sodium hydroxide is added is prepared and brought into contact with aluminum in a reaction vessel. The present invention is characterized in that the temperature in the reaction vessel is raised to 25 ° C. or higher only by the heat of reaction between the aqueous sodium hydroxide solution and aluminum without using a heating means for applying heat from the outside of the reaction vessel. is there. The present invention is characterized in that the temperature in the reaction vessel is set to 25 ° C. or higher by the reaction heat between the aqueous sodium hydroxide solution and the aluminum. The present invention is characterized in that the concentration of sodium hydroxide in the aqueous sodium oxide solution is 0.1% or more. The present invention is characterized in that the concentration of sodium hydroxide in the aqueous sodium hydroxide solution is 0.1% ≡3% or more. The present invention comprises a reaction vessel for containing aluminum and aluminum addition means for introducing aluminum into the reaction vessel in order to bring the water modified in the reaction vessel and aluminum into contact with each other. The aluminum charged into the reaction vessel is converted into aluminum oxide powder after hydrogen generation, and the aluminum changes. The aluminum to be added is a cartridge type and can be easily replaced in the reaction vessel, and the changed aluminum oxide powder is separated in the cartridge and taken out in a recoverable state. It is a device that can be used. Further, the present invention is characterized in that the aluminum is introduced into the bottom of the reaction vessel, and the liquid level of the aqueous sodium hydroxide solution is higher than the uppermost level of the aluminum. In addition, the water that comes into contact with the aluminum can be brought into contact with the water as well as being poured into the tank in a stationary state. There is also a method in which water is continuously brought into contact with fixed aluminum. On the contrary, aluminum can be continuously brought into contact with water to carry out the reaction continuously in an arbitrary state. By doing so, the reaction can be repeated at an arbitrary time by repeatedly stopping the reaction or starting the reaction. In addition to reacting with this modified water and aluminum, in addition to magnesium, it is possible to simultaneously generate hydrogen by electrolysis by providing an electrode in the tank in the modified water at the same time in order to accelerate the reaction. It becomes possible. In addition to the electrode, aluminum also reacts to generate a large amount of hydrogen from the aluminum that is charged with electricity. At this time, water in which hydrogen, oxygen, and water move in a manner similar to the state of the subcritical point is mixed, and the hydrogen concentration can be arbitrarily increased or oxygen-hydrogen gas can be generated. It is a gaseous substance in the state of oxygen-hydrogen gas HHO. It is also called brown gas.

The material used in claim 1 of the method for producing hydrogen according to the present invention uses only two kinds of materials of commercially available aluminum and modified water, and the temperature in the reaction vessel is set to 25 ° C. or higher. By doing so, hydrogen is generated. In the present invention, hydrogen can be produced at a very low cost by using only aluminum and modified water without using a chemical agent or a metal other than aluminum as a main material.

The modified water used in the present invention contains a large amount of hydrogen atoms such as hydroxyl ions (H3O2−), hydroxide ions (OH +) and hydrogen ions (H +). Since aluminum is an electrode amphoteric element, when the modified water reaches a temperature of 25 ° C or higher, many positive and negative electrodes appear in the aluminum, and the positive and negative electrodes generate a weak current. Thus, it is presumed that electrolysis of the reformed water in the reaction vessel is promoted and a large amount of hydrogen is generated from the reformed water. Furthermore, since the time for generating hydrogen from the reformed water is long, a large amount of hydrogen can be generated. It is presumed that the present invention has the effect of delaying the formation of a film on the surface of aluminum by hydroxyl ions (H3O2-) as a typical state contained in the modified water.

In the present invention, when hydrogen is generated by bringing modified water and aluminum into contact with each other in a reaction vessel, the heating temperature of the reaction vessel is 25 ° C. or more and lower than the boiling point of the reformed water. The reaction vessel can be heated at. Since it is heating under atmospheric pressure, it is inexpensive and simple without requiring a special device that has to raise the temperature to 3,000 ° C. to 5,000 ° C. like conventional thermal decomposition of water. Hydrogen can be generated with a simple device. When heating the aluminum in the reaction vessel and the reformed water using a heating means, the generation of hydrogen can be stopped by stopping the contact between water and aluminum and stopping the heating. . Therefore, it is possible to quickly generate and stop hydrogen, and it can be applied to various devices that use hydrogen as fuel.

If the reaction vessel containing the reformed water and aluminum is once heated to 25 ° C or more to generate hydrogen, and then the new water is brought into contact with the reformed water (if placed in the reaction vessel) The temperature in the reaction vessel is maintained at 25 ° C. or higher, and hydrogen is continuously generated by the contact between the reformed water after the generation of hydrogen and new aluminum, without heating by the heating means. Thus, since hydrogen is continuously generated without using a heating means, the fuel cost for heating can be saved. This is because neutral or alkaline modified water reacts with aluminum to generate part of the hydrogen, and then the modified water becomes alkaline, so that the alkaline water in the reaction vessel is not heated by heating means. The reformed water reacts with the newly added aluminum, the temperature in the reaction vessel is maintained at 25 ° C. or higher, and hydrogen is continuously generated. In addition, when aluminum is used as a powder, the amount of hydrogen generated greatly increases.

Aluminum is put into the reaction vessel, and the uppermost layer of aluminum is covered with modified water or an aqueous sodium hydroxide solution. That is, if aluminum is immersed in modified water or an aqueous sodium hydroxide solution, the generation of an oxide film on the surface of aluminum is delayed by hydroxyl ions (H3O2−) contained in the modified water. And the generation time of hydrogen can be lengthened.

Instead of only the modified water, an aqueous sodium hydroxide solution in which sodium hydroxide is mixed with the modified water may be used. When an aqueous sodium hydroxide solution in which sodium hydroxide is mixed with modified water is used, reaction heat is generated by bringing the aqueous sodium hydroxide solution and aluminum into contact with each other in the reaction vessel. The reaction heat can raise the temperature in the reaction vessel to 25 ° C. or more by self-heating, and hydrogen can be generated in the reaction vessel without using a heating means for applying heat from the outside of the reaction vessel. . The reaction heat of aluminum and sodium hydroxide aqueous solution raises the temperature in the reaction vessel and the hydrogen is generated in a large amount from 25 ° C to 80 ° C. Can do. The temperature of the heating means for applying heat from the outside of the conventional reaction vessel is 600 ° C. to 5,000 ° C., which requires expensive equipment, but in the present invention, the heating means for applying heat from the outside of the reaction vessel is omitted. In addition, only an aqueous sodium hydroxide solution obtained by adding sodium hydroxide to modified water and aluminum are used, and hydrogen can be produced at low cost. The present invention generates hydrogen by self-temperature rise by reaction heat, and does not use a heating means for applying heat from the outside of the reaction vessel or electricity. Therefore, an apparatus according to this hydrogen generation method is provided. It can be mounted on an automobile or the like.

In the method for producing hydrogen of the present invention, by using a sodium hydroxide aqueous solution in which sodium hydroxide is mixed with reformed water, the amount of hydrogen generated is increased as compared with the case of only reformed water, and oxygen is increased. Generation amount can be greatly reduced. When the generation ratio of oxygen is lowered as much as possible, a method for separating oxygen from a gas containing hydrogen and oxygen can be simplified, and the cost for producing hydrogen can be reduced.

In the hydrogen generator of the present invention, alkaline modified water that generates hydrogen only by contacting with aluminum without using a heating means is used. Water that generates hydrogen only by contacting with aluminum is water after it has been brought into contact with reformed water and aluminum, and once heated from 25 ° C. to 80 ° C. to generate hydrogen (becomes alkaline). Or a sodium hydroxide aqueous solution in which special water and sodium hydroxide are mixed. A mounting member (cartridge) for placing aluminum is accommodated in a reaction vessel for containing alkaline modified water and aluminum, and the reaction is performed such that the mounting member is above the bottom surface in the reaction vessel. Place in container. The aluminum on the mounting member melts and changes to aluminum oxide by reacting with alkaline modified water.

The level of the raw water 11a is constantly measured and replenished so that the aluminum cartridge 12 is always held in the raw water 11a. In addition, a relief valve 14 is provided at an appropriate position so as to release the gas pressure when the atmospheric pressure in the reaction tank 11 increases excessively. The hydrogen gas generated in the reaction vessel 11 is sent to the separation tank 15 and only the hydrogen gas is taken out, and can be stored in the vacuum storage tank 17 at the same pressure as the pressure generated by the reaction. If necessary, the hydrogen gas can be fed into the storage tank 17 in a state of being pressurized by the compressor 16 or the like. Further, the electric power can be stored by the battery 19 after being generated by the engine generator 18. Reference numeral 20 denotes a control panel for controlling the whole.

Further, the pressure at which hydrogen generated by the reaction is transferred to the storage tank 17 and stored is about 2 to 3 atmospheres. Then, the stored hydrogen can be stored at an arbitrary pressure by a compression pumping device. The hydrogen storage tank 17 to which pressure is applied can be arbitrarily adjusted in pressure, and the hydrogen can be appropriately discharged. Hereinafter, the method for producing hydrogen of the present invention will be described in detail based on a plurality of examples.

Exhaust gas discharged from an engine started with hydrogen is different from gasoline-type exhaust gas, and water or water vapor is discharged from the exhaust gas as exhaust gas. Also, it can be used for a device for burning hydrogen gas as it is, for example, a cooking utensil such as a gas stove. When hydrogen gas using the present technology is specified for a combustion apparatus, modification of the combustion apparatus is required for the existing apparatus.
