摘　　要：传统的煤直接液化铁系催化剂的研发已达到纳米级和超高分散性的水平,但铁系催化剂的加氢性能相对钼、镍等有色金属催化剂要弱,而钼、镍等加氢催化剂与铁系催化剂的复合使用有一定的协同作用。针对钼、镍等加氢催化剂与铁系催化剂的复合使用进行调研,发现目前该复合型催化剂领域研究较少,且均停留在实验室阶段,而该催化剂的制备方法较为复杂,不利于现有催化剂制备工艺的改进和放大,有进一步研究的必要。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.
