,The First-Generation Catalyst for Selective Hydrogenation of Benzene to Cyclohexene-Ru–M–B/ZrO2(M=Fechnologies were transferred to our country in 1995 and 2005, respectively. The main technical indexes of the first-generation catalyst were as follows: the conversion of benzene was 40%, the selectivity of cyclohexene was 80%, and the yield of cyclohexene was 32%. For the second-generation catalyst

The Second-Generation Catalyst for Selective Hydrogenation of Benzene to Cyclohexene-Ru-Zn-Na2SiO3-of cyclohexene was over 80%, yield of cyclohexene was more than 42%, reached the second-generation of similar catalyst level abroad. Compared with the first generation amorphous alloy Ru-M-B/ZrO., the second-generation catalyst belongs to the crystalline structure with better thermal stability and l
