Optimization of Furfural Production from Xylose by RSM Using Chromium Sulfate as Catalyst

Abstract:

Optimization of chromium sulfate catalyzed conversion conditions of xylose into furfural was studied by response surfacemethodology (RSM). A central composite design (CCD) was used to determine the effects of independent variables, including temperature (120-160°C), time (30-150min), catalyst loading (1-5mmol) and moles of xylose (2.5-12.5mmol) on furfural yield, xylose conversion and solid residue. The surface response analysis revealed that temperature, time, catalyst loading and moles of xylose had a strong influence on the furfural yield, whereas moles of xylose was found to be notsignificant for xylose conversion. The solid residue was affected by temperature, time and moles of xylose. The maximumpredicted furfural yield was 45.07% at temperature of 150°C, time of 12min, catalyst loading of 2 mmol and moles of xylose of 10mmol. Under this condition, xylose conversion could be reached 100%.
