| 제목 | Studies on the Hydrogenolysis of Glycerol to 1,2-Propanediol over Bimetallic Ni-Cu Based Catalyst |
| 초록 | Recently, the production of glycerol has been increased with the production of biodiesel as a clean fuel. One of the most attractive approaches of converting glycerol is to produce propanediol(1,2- or 1,3-PDO) by selective hydrogenolysis of glycerol. The Ni-Cu based catalysts were prepared by impregnation method, and characterized by N2 physisorption, CO chemisorption, XRD, SEM, TPR and TPD. The catalytic hydrogenation of glycerol to 1,2-PDO was investigated at 463 K, 25 bar of initial H2 pressure and 10 wt% glycerol aqueous solution for 6 h. It was found that the Ni-Cu/γ-Al2O3 catalyst with glycerol conversion of 70 % and 1.2-PDO selectivity of 95 % showed the best activity than any other catalysts. The results show that Ni provides comparatively high hydrogenolysis activity of C-C and C-O bonds and the formation of Ni-Cu alloy limits C-C hydrogenolysis and promotes C-O hydrogenolysis. |
