摘要
Abstract
A new process for the overlapped coupling between coal gasification and C1ynthesis was proposed, which was in the coal gasification process, hydrocarbons were synthesized from the newly generated carbon monoxide and hydrogen on the coal surface with porous structure. The thermodynamic analysis showed that there were nine independent reactions in the reaction system. Parameters of the independent reactions were obtained by atom matrix analysis. All the curve slopes of Gibbs free energy changes of the reactions with temperature were negative. The temperature rise was beneficial to synthesis of the hydrocarbons with more carbon atoms. C2-4 content in the equilibrium composition indicated the greatest value near 900 K. Appropriate increase of the pressure could raise the hydrocarbon content and the high feed mole ratio ( n ( H2 O) : n ( C)) was unfavorable to the increase of the light olefin yield.关键词
