Description
Technical field
The present invention relates to a kind of fuel generation system and generation method thereof, particularly a kind of fuel generation system and generation method thereof that is applied to the power station.
Background technology
After Englishman watt improvement steamer in 1765, tradition is then pushed to take machinery as the main epoch take manpower or animal power as main back yard industry.Especially after watt research and development rotary steam engine in 1782 success, use so that steamer can be widely applied to mining, weaving, train and steamer traffic, opened the human Industrial Revolution.Until American inventor Edison applying steam machine in 1881 promotes direct-current generator, thereby set up global First central type power station, so that produce the technology fast development of electric power with steam engine-generator, but the discharging that also brings great amount of carbon dioxide as the fuel-burning power plant of main steamer-generator take fossil fuel (coal, oil or Sweet natural gas), cause global warming and climatic variation so that the extreme climate variable effects such as heat wave, flood and arid the human lives; Therefore, whole world scientist endeavours to seek the mode that solves Carbon emission, capture and seal up for safekeeping, particularly research and develop the science and technology of killing two birds with one stone, for example carbonic acid gas is sealed up for safekeeping in oil field or the natural-gas field, wish that the carbonic acid gas of sealing up for safekeeping can make day by day exhausted oil field or natural-gas field again spray future, the two large problems that therefore can solve simultaneously Carbon emission and solve lack of energy.
Various carbonic acid gas captures the mode of sealing up for safekeeping and then arises at the historic moment, such as with carbon dioxide absorption, absorption, subzero treatment or the divided thin film of chemistry or physics from etc. method with the carbonic acid gas acquisition, separate and store, seal up for safekeeping at the bottom of the ground or the seabed in the high pressure mode again; Yet the mode that this kind high pressure is sealed up for safekeeping so that the envelope method of depositing of geology is under suspicion, easily makes the carbon dioxide leakage of sealing up for safekeeping because of the impact of the factors such as earthquake in atmosphere and ocean easily because of earthquake, cause the shortcomings such as acidifying and anoxic.If carbonic acid gas is processed with biological process, for example be with the carbon source of carbonic acid gas as green alga, and utilize sun power to carry out photosynthesis, can produce living mass-energy for changing into biodiesel, giving birth to the fuel such as matter gasoline or living matter alcohols; But because of carbonic acid gas and carbon monoxide tool bio-toxicity, so that the carbonic acid gas Plugging Technology Applied of green alga also is under suspicion with area, wastewater treatment and biological the murder by poisoning in algae.
Although carbonic acid gas be cause global warming greenhouse gases one of them, but carbonic acid gas also is human indispensable industrial chemicals, be used for IQF food, utilize carbon-dioxide fire engine, use carbon dioxide welding or adopt carbonic acid gas as industrial lasers gas etc. such as carbonic anhydride bubble drink, solid carbon dioxide, and the green plants in the Nature also with carbonic acid gas as photosynthetic carbon source.And, carbonic acid gas also can be used as Pressure filling gas, produce urea for soil nitrogenous fertilizer, Co 2 supercritical fluid is used etc., especially in recent years carbonic acid gas is through catalyst Synthesis methane, methyl alcohol, dme, aldehydes, fuel and the chemical industry energy that acids or urea etc. are valuable, but traditional chemistry and membrane by accelerant process are to utilize burning to obtain, and because carbonic acid gas is very stable and reactivity is poor, need to obtain the energy from the outside and activate carbonic acid gas, cause utilizing carbonic acid gas to produce as raw material in the process of fuel, the amount of carbon dioxide that the amount of carbon dioxide specific consumption that the manufacturing extra power produces falls is also more; Therefore, the scientist in the whole world all endeavours to meet carbonic acid gas decrement demand in searching one, and do not adopt the reduction technique of highly energy-consuming, to avoid making more carbonic acid gas, therefore take gibbs (Gibbs) free energy and Helmholtz (Helmholtz) free energy as core, to seek in thermodynamic process, can be converted into the part of external work done in the interior energy that system reduces.
Carbon dioxide conversion is being become in the mode of fuel, after for example utilizing carbonic acid gas and hydrogen synthesizing methane, the further mode of synthol again, because it is infeasible at thermodynamics that methane direct conversion becomes higher hydrocarbons, because preparing methanol fuel, methane needs high-temperature catalytic, belong to the highly energy-consuming process, the carbonic acid gas that its catalysis produces is also higher than the amount that makes the carbonic acid gas of using up, and therefore makes carbon dioxide conversion become the technical development of fuel to stagnate always.
Present global scientist is greatly mainly with the mutual mode of using of various energy resources, for example in the fuel-burning power plant, with electric power or chemical mode acquisition carbonic acid gas, again with electric power or chemistry wait the power consumption mode with carbon dioxide separation, reclaim and storage, produce heat energy for the catalyst reaction with fossil fuel, electric power equal energy source again, to prepare the fuel such as methane or methyl alcohol, in its loaded down with trivial details reaction and step, the power consumption flow process that electric power and fossil fuel produce and the carbonic acid gas of manufacturing are all considerably beyond recoverable amount of carbon dioxide.
According to the requirement of the Kyoto Protocol to the carbon dioxide greenhouse gas decrement, impel the whole world to stride forward towards the target of the renewable energy resources and high energy gamma source, the target that carbonic acid gas decrement and energy regeneration are sought in hope, wherein with the primary problem of water coal method as fuel-burning power plant of new generation, with coal, water produces synthetic gas (carbon monoxide and hydrogen) through vaporization reaction, as carbon source and hydrogen source material, make catalyst produce catalyzed reaction through heat (activation energy), form available ethanol, methyl alcohol, the fuel such as methane, the recycling preparing low-carbon olefin by using methanol, ethene for example, propylene, the raw materials such as dme, be catalyzed into high-carbon fuel (such as oil through catalyst again, diesel oil), the petrochemical industry chain that synthetic gas is become can substitute crude oil significantly lowers the exhausted problem of crude oil (petrochemical industry).But, the coal water vapor produces synthetic gas to fuel and low-carbon alkene (chemistry, industrial chemicals) needs multi-level catalyst catalytic oxidation-reduction reaction in the process, such as oxidation catalyst, reducing catalyst, hydrogenation catalyst and dehydrogenation catalyst etc., before will reacting with catalyst, synthetic gas also need reach the activation energy stagnation point of catalyst, catalyst could begin reaction, and this activation energy often needs the energy with the outside, such as heat energy or the unsettled renewable energy resources, such as sun power, wind energy, tidal energy, give birth to mass-energy, Geothermal energy, water power or nuclear energy steam etc., just can carry out the required electrochemical reaction of catalyst, photoelectrochemistry reaction and thermal chemical reaction etc., make the coal in fuel-burning power plant, the water vapor synthetic gas can carry out electrochemistry or photoelectrochemistry or thermochemistry via the energy can activate catalyst, synthetic valuable alcohol, alkane, ether fuel or low-carbon alkene (ethene, propylene) chemistry/industrial chemicals such as.
At present external clean coal technology is with the coal gasification circulating generation, utilize coal, multiple cycle generating system (the Integrated gasification combined cycle of the gasification that residual oil or refinery coke act as a fuel, IGCC), its usefulness is 43%-50%, and the synthetic gas that outside generating, can utilize water-gasification to produce, through FT reaction (Fischer-Tropsch synthesis) synthesizing methanol, dme, diesel oil or hydrogen etc., also can be used as more good speed in conjunction with fuel cell etc., but still have 50% the energy to be discharged when waste gas used heat, and need again the mat extra power to carry out synthesizing of fuel and industrial chemicals.
Looking about existing flare system, mainly is to utilize the burning of fossil fuel in the power station and when generating electricity, the waste gas that burning produces is done further processing, uses and reduces the pollution that exhaust gas emission causes.
In view of this, waste gas and used heat that the power station that the present invention will utilize fossil fuel to generate electricity discharges are reclaimed, and through catalyst reaction and synthol or industrial chemicals are used the energy is effectively utilized, and then reduce the discharging of waste gas and used heat.
