| Abstract: | 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. |
