【摘要】采用共沉淀法制备用于甘油催化氢解制1,3-丙二醇的纳米CuO-
TiO2/SiO2催化剂,用X射线粉末衍射及扫描电子显微镜对催化剂的结构及形貌进行表征.在微型固定床反应器上考察了纳米催化剂对甘油氢解制备1,3-丙二醇的催化性能,结果表明,在反应温度190℃、H2压力4.5 Mpa、n(H2)∶n(甘油)=50∶1和液空速0.30 h-1的较佳条件下,甘油转化率为35.66％,1,3-丙二醇选择性达78.18％.%Nano CuO-TiO2/SiO2 copper-based catalyst was prepared by co-precipitation method and was used in the catalytic hydrogenolysis of glycerol to 1 , 3-propanediol in a fixed bed microreactor. The structure and morphology of the catalyst were characterized by XRD and SEM. The catalytic performance of the catalyst for hydrogenolysis of glycerol was investigated. The results showed that glycerol conversion of 35.66% and the selectivity to 1,3- propanediol of 78. 18% were attained under the optimum condition as follows:reaction temperature 190 °C ,hydrogen pressure 4.5 Mpa,n( hydrogen) : n( glycerol) =50: 1 and liquid hourly space velocity 0. 30 h-1.
