Liquid Phase Hydrogenolysis of Glycerol over Highly Active 50%Cu–Zn(8:2)/MgO Catalyst: Reaction Parameter Optimization by Using Response Surface Methodology

摘要: In this study, a highly promising bimetallic 50%Cu–Zn(8:2)/MgO catalyst was developed for selective hydrogenolysis of glycerol to 1,2-propanediol (1,2-PDO). The catalytic activity evaluated in high pressure autoclave reactor. Results demonstrated that the incorporation Zn into Cu/MgO catalysts enhanced conversion and selectivity 1,2-PDO due hydrogen spillover effect. Experimentally maximum 98.7% with 94.6% achieved at mild reaction conditions. Response surface methodology (RSM) employed study interaction various parameters develop an empirical process model followed by optimization parameters. values determination coefficients (>0.95) obtained analysis variance indicated quadratic regression models were satisfactory. results numerical 97.8% 93.5% 1,2-PDO...
