Hydrogenolysis of sucrose was carried out using Ni,W,Cu/ kieselguhr catalyst in aqueous solution under hydrogen gas atmosphere 50 atm. The effects of catalyst reduction temperature, catalyst reduction time and amount of catalyst used for reduction were evaluated by using response surface methodology. A linear second order model has been developed to study the effects of selected independent variables on glycerol yield. The yield of glycerol increases with increasing catalyst reduction temperature, catalyst reduction time as well as amounts of catalyst used for reduction. The maximum glycerol yield (39.02%) was obtained with catalyst reduction temperature (673.9 oC), catalyst reduction time (4.3 h) and amount of catalyst used for reduction (7.80 g).
