| Abstract: | 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. |
