Catalytical Performance of Supported Nano-amorphous Alloy NiB/MCM-41 on Hydrogenation of Rosin
摘要
Abstract
Hydrogenation of rosin catalyzed by supported nano-amorphous alloy NiB/MCM-41 prepared by chemical reductive deposition method was investigated.The catalyst showed excellent catalytic activity for hydrogenation of rosin.Under the optimum conditions for hydrogenation of rosin i.e.load volume of Ni 13%-15%(mass fraction),H2 pressure 7-9 MPa,reaction temperature 180-190℃,reaction time 5 h,the contents of dehydroabietic acid(DEHAA)and abietic acid(AA)in the product were less than 2.5% and 0.5% respectively.The distribution of hydrogenation products remained basically stable during the repeated using of the catalyst.The amorphous alloy structure of NiB active sites,typical mesoporous structure and hish BET area in the prepared catalyst had been proved by XRD,TEM,EOAX,ICP and N2 adsorption-desorption.关键词
