摘要
Abstract
Supported Cu catalysts were prepared by wetness impregnation method and used in the hydrogenolysis of glycerol to 1,2-propanediol. The catalysts were characterized by means of XRD, H2-TPR and NH3-TPD and the influence of temperature, pressure, reaction time and catalyst reusing on its catalytic activity in glycerol hydrogenolysis was investigated. The results showed that the catalytic activity is strongly dependent on the support and proper acidity is essential for the hydrogenolysis. 8Cu/γ-Al2 O3 catalyst exhibits high activity and stability; after reaction over it for 6 h under the optimal reaction conditions of 513 K, 6 MPa, catalyst amount of 2.5 % , with 10 % glycerol aqueous solution as feed, the conversion of glycerol and the selectivity to 1,2-propanediol reach 88.4% and 86.2% , respectively.关键词
