Based on the development status of catalysts for direct coal liquefaction,a new type of pillared montmorillonite catalyst was prepared through pillaring technique using montmorillonite as catalysts support,Fe and Cr,Co,Ni as active hydrogenation components. The advantages of pillared montmorillonite catalyst in direct coal liquefaction technique was analyzed,the domestic and foreign research progress of the pillared montmorillonite's preparation technique was reviewed. The main preparation process of new typepillared montmorillonite catalyst was summarized. Finally,the key factors which affected the catalytic activity and thermal stability of the pillared montmorillonite were pointed out. The results showed that,the pillared montmorillonite catalyst obtained by pillaring active hydrogenation components into the montmorillonite layer had excellent catalytic hydrogenation performance. The optimization of pillaring process,the development of catalyst with good thermal stability,and the adjustment of pore size distribution was the focuse in the future.
