摘要
采用共沉淀法制备了纳米CuO/SiO2催化剂,在固定床反应器上考察了纳米催化剂对甘油催化加氢制1,2-丙二醇(1,2-PDO)的催化活性。结果表明,在反应温度200℃,反应压力1.0 MPa,n(H2)∶n(甘油)=30∶1,液空速0.30 h-1的条件下,甘油转化率100%,1,2-PDO选择性98.71%。
Nano CuO/SiO2 copper-based catalyst was prepared by a co-precipitation method.The effect of nano catalyst on 1,2-propanediol（1,2-PDO） by hydrogenolysis from glycerol in the fixed bed reactor was studied.The results of catalytic hydrogenolysis of glycerol to 1,2-propanediol on the nano catalyst indicated that the conversion of glycerol was 100%,while the selectivity of 1,2-propanediol was 98.71% under the following reaction conditions：reaction temperature 200 ℃,H2 pressure 1.0 MPa,n（H2） ∶n（glycerol）=30 ∶1,and liquid hourly space velocity 0.30 h-1.
