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 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 high BET area in the prepared catalyst had been proved by XRD,TEM,EOAX,ICP and N₂ adsorption-desorption.
