摘要： 将采用化学还原沉积法制备的负载型非晶合金NiB/MCM-41中孔分子筛催化剂用于松香的氢化反应,表现出很高的加氢催化活性.研究确定在Ni负载量为13%～15%、反应温度180～190℃、反应压力7～9 MPa条件下加氢反应5 h,去氢枞酸(DEHAA)、枞酸(AA)在加氢产物中的含量分别小于2.5%和0.5%,且在催化剂重复使用过程中加氢产物分布基本保持稳定.分别采用XRD、TEM、EDAX、ICP和比表面测定等手段对催化剂进行了表征.研究表明:NiB活性组分具有非晶结构特征、催化剂具有典型的中孔结构和较大的比表面积.

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.
