Description
Technical field
The invention belongs to the energy and chemical field, relate in particular to a kind of catalyzed and gasified coal-based energy chemical product polygenerations systeme and method.
Background technology
In world's primary energy source consumption, coal is fastest-rising fuel, surmounts the growth that oil and natural gas is realized the market share for years.But coal also is the highest fossil oil of carbon content, in burning and conversion process, produce great amount of carbon dioxide inevitably, and Carbon emission has been paid close attention to by the world to the influence of Global climate change, so it is very urgent to solve the problem of Carbon emission.
" rich coal, few oil, deficency " is the basic characteristics of China energy resource structures.In China's fossil energy total amount, 95.6% is coal, and coal production, consumption rank first in the world for successive years.This energy structure has determined Chinese primary energy source to be difficult to change in quite long period based on the general layout of coal.Yet there are problems such as the coal resources comprehensive utilization ratio is very low, discharging great amount of carbon dioxide in traditional coal mining and utilize mode, in addition, and the not fine as yet development and utilization of brown coal of 1,290 hundred million tons of reserves of China.Therefore, the development of new coal chemical technology is badly in need of in China, changes traditional coal mining and use-pattern, and efficient, cleaning, utilization comprises the coal resources that enrich of brown coal safely.
Catalytic coal gasification is that coal and water vapor generate methane under the effect of catalyzer, carbon monoxide, effective constituent and carbonic acid gas such as hydrogen, a spot of hydrogen sulfide and ammonia.Catalytic coal gasifaction generally adopts fluidized-bed, compare with other gasifying process, this technology has can be without oxygen production methane, methane content is higher, temperature of reaction is lower, can gasification take place simultaneously in the vapourizing furnace, not have independent transformationreation and methanation reaction, and conversion section and methanation workshop section needn't be set, large-scale fluidized bed use will improve turnout, reduce investment outlay greatly.Owing to do not need oxygen, ashes slagging scorification problem is uncomplicated, can realize draining continuously slag, and the recovery of catalyzer simultaneously is simple, and gas residence time in vapourizing furnace is long, and catalyzer also can stop the generation of tar.Gasifier temperature is lower, requires also not harsh to reactor material and mechanical workout etc.But also there is following shortcoming in this technology, and catalyzer can not stop weak coking fully, and the actual conversion of carbon is no more than 90%, produces great amount of carbon dioxide gas in the reaction, can not solve the emission of carbon-dioxide problem.
CN101024783A has announced a kind of chemical-power multi-combined production production system, this system adopts crude synthesis gas, and directly chemical industry is synthetic after cooling, purification, a reacted synthetic gas part is used for circulation, and another part is used for fuel and sends into the Gas combined cycle system and generate electricity.This system's main purpose is to utilize the synthetic gas waste heat to reach energy-saving effect, does not solve CO
2The problem of discharging can not realize ecological circulation production.
When producing firedamp by syngas, methyl alcohol, ethylene glycol, low-carbon alcohol or dme etc., need usually to regulate hydrogen-carbon ratio (as in synthetic gas, adding certain amount of H
2).Though about 96% industrial hydrogen derives from fossil energies such as Sweet natural gas, oil and coal at present, use the production technology and the technology of fossil energy hydrogen manufacturing can not solve CO
2Emission problem, thereby can not realize ecological circulation production.In other hydrogen producing technology, water electrolysis hydrogen producing is to use one of wider and sophisticated relatively hydrogen production process at present.It is at present tool prospect and the most feasible technology that the electric energy (comprising sun power, wind energy etc.) that utilizes renewable energy source to produce comes water electrolysis hydrogen producing as power, is called as the optimal path that leads to hydrogen economy.But water electrolysis hydrogen producing and catalytic coal gasifaction coproduction yet there are no report at present.
To sum up, the chemical poly-generation of coal-based energy technology that countries in the world are developed does not in succession all have system to consider carbonic acid gas recycling problem, how to control and reduce coal transform and combustion processes in the carbonic acid gas that produces, and with its recycling, though become the matter of utmost importance of novel coal chemical technology development. in view of the seriousness of " Greenhouse effect ", American-European countries's coal-based near zero release polygenerations systeme that begins one's study in recent years, but because the carbonic acid gas chemical property is stable, this coal-based near zero release polygenerations systeme can't be realized carbon dioxide discharge-reduction in process of production, can only adopt the method that captures and seal up for safekeeping to go to solve, and this method is with high costs, can not really reduce carbonic acid gas from measuring, long-range it seems only is makeshift. thoroughly solve the problem of carbonic acid gas, just must break through the limitation of existing fossil energy, renewable energy source is introduced the production process of coal derived energy chemical product, realize the fusion in multipotency source, carbonic acid gas is converted into derived energy chemical product, thereby realizes the production process near zero emission of CO.
