Abstract：Traditional Fe-based catalyst on direct coal liquefaction has been highly developed, which is nanometer grade and highly dispersed.Compared with the Ni-, Mo-based catalyst, the Fe-based catalyst is weaker on hydrogenation.And the studies have shown that the synergism has been found by using both kinds of catalysts. The paper was focused on this kind of composite catalyst.It was also investigated that the comparatively few research of this composite catalyst remained in laboratory stage, and some of the catalyst preparation was too complex to improve the available preparation process and scale-up of the catalyst.This kind of composite catalyst should be a trend in future.
