煤催化气化催化剂及其催化机理研究进展

A Research Progress on Catalysts and Catalytic Mechanism of Coal Catalytic Gasification

煤的催化气化对煤的高效洁净转化,实现我国能源和环境的可持续发展具有非常重要的意义。从煤气化催化剂(一元、多组分及可弃催化剂)和催化反应机理方面进行了综述。指出多组分催化剂催化效率高于一元催化剂,但其回收利用是经济生产的关键,可弃催化剂价格低廉,但催化活性较低,活性点(位)理论在煤的催化机理中具有一定的代表性,并对煤催化气化的发展方向进行了展望。

Coal catalytic gasification is an important significance to utilize coal cleanly, to reduce energy consumption and to realize the sustainable development of energy resource and the environment in China. The research of coal catalytic gasification was summarized from the types of catalyst （ one component, multicomponent, and disposable catalyst） and catalytic reaction mechanism. It is pointed that the catalytic efficiency of multicomponent catalyst is higher than that of one component catalyst, but its reuse is the key to economic production; while the disposable catalyst has low price, but the catalytic activity is lower. The development direction of the catalytic gasification of coal is prospected.
