摘要:
A method for preparing sugar alcohols by using a ruthenium zirconia catalyst is provided to allow continuous product of high-purity sugar alcohols under a mild condition of a low temperature and low pressure without dissolution of the catalyst component, and to reduce generation of side products and waste. A method for preparing sugar alcohols comprises a step of carrying out hydrogenation of sugars by using a catalyst comprising ruthenium supported on a zirconia carrier with a dispersity of at least 10% and having a chlorine content less than 100 ppm, at a reaction temperature of 20-150 deg.C under a reaction pressure of 5-300 kg/m^2 to obtain the corresponding sugar alcohols. The carrier has a surface area of 10-500 m^2/g, and the catalyst comprises 0.1-10 wt% of ruthenium based on the total weight of the catalyst.
