摘要
过渡金属碳化物作为一种催化新材料得到了人们广泛的关注，在催化加氢、脱氢、脱硫（HDS）、脱氮（HDN）和重整等方面，表现出优良的催化活性和选择性。本文综述了碳化钒、碳化钼、碳化钨、碳化铁、碳化钛等碳化物的催化性能在国内外的研究进展和碳化物在各个反应中的催化机理。
The transition metal carbides have been extensively studied as a new class of catalysts, due to their attractive advantages in catalysis. The catalytic activity and selectivity of transition metal carbides are excellent, especially catalysts for hydrogenolysis, dehydrogenation, hydrodenitrogenation, hydrodesulfurization, alkane isomerization and a variety of other hydrocarbon conversion reactions. In this paper, the catalysis of transition metal carbides including VC, Mo2C, WC, FeC, TiC and the mechanism of all the reactions were reviewed.
