摘　　要：煤直接液化工艺中催化剂作用十分重要,粒径小、分散性高的催化剂能够有效提升煤转化效率。将流动反应介质中小颗粒的固体催化剂命名为分散相催化剂,综述煤直接液化中常用的几种分散相催化剂,包括金属卤化物催化剂、过渡金属氧化物催化剂和铁系催化剂,提出可能的催化机理。The catalysts during the direct coal liquefaction reaction are very important.Catalysts with small particle size and high dispersion can effectively improve the reaction conversion.The solid catalysts with small particle size in the flowing reaction medium are named as dispersed phase catalysts.This context summarized several kinds of dispersed phase catalysts,which were commonly used in the direct coal liquefaction,including metal halide,transition metal oxide,and iron-based catalysts.In addition,possible reaction mechanism of coal direct liquefaction was also summarized.
