摘要：

The conversion of bio-based xylitol to ethylene glycol (EG) and propylene glycol (PG) was studied to replace the petrochemical production route and achieve a sustainable process. The reaction network for aqueous-phase catalytic hydrogenolysis of xylitol over a supported Pt catalyst with Ca(OH)(2) as promotor was identified and the reaction kinetics was determined. The effects of reaction conditions such as educt concentration, H-2 pressure, and temperature were investigated. With the developed kinetic model, the composition of the product mixture regarding the desired products (EG, PG) and by-products can be described. The maximum EG yield was achieved at high pressure and low temperature, while high pressure and temperature favored PG production.
