碳二选择加氢催化剂研究进展

简要分析了国内外碳二馏份选择加氢脱乙炔的工艺现状，又从载体、助催化剂和催化剂失活等方面介绍了碳二馏份选择加氢的研究进展，指出提高选择性、降低投资、节能降耗是乙烯工业发展的总趋势。

Second Choice of Carbon Hydrogenation Catalysts

This paper analyzes the domestic and international carbon fraction second choice from acetylene hydrogena-tion process of the status quo,from the carrier,catalyst and catalyst deactivation of these three areas,introduced two carbon fraction of the selective hydrogenation study progress to improve selectivity and reduce investment,saving ener-gy and reducing consumption of ethylene is the general trend of industrial development.
