Effect of the Nature of Ni Species on Hydrogenation of 1,4‐Butynediol over Ni/SiO2 Catalysts

et al.

Abstract: The catalytic performance of liquid‐phase hydrogenation of 1,4‐butynediol (BYD) to 1,4‐butanediol (BDO) was studied on silica‐supported Ni catalysts prepared by impregnation, sol‐gel, and ammonia evaporation methods, respectively. Due to the formation of nickel phyllosilicate, the Ni species in Ni/SiO2‐AE catalyst prepared by ammonia evaporation is difficult to reduce at 450 oC, resulting in fewer Ni0 active sites and poor hydrogenation activity. As for the impregnated Ni/SiO2‐IM, its nickel particles are pron… Show more
