Abstract: With the diminishing resources of fossil fuels,searching for sustainable,alternative energy is critically important. In this paper,the recent advances in catalytic hydrogenolysis of sugar alcohols to lower polydric alcohols are reviewed. Ethylene glycol,glycerol,1,3-propylene glycol could be obtained with high selectivity by hydrogenolysis of sugar alcohols. Emphases are laid on the Retro-aldol,Retro-Michael reaction mechanisms and copper,nickel,noble metal based catalysts for the hydrogenolysis of sugar alcohols. The review shows that the future research should be focused on the development of more effective and stable catalysts,the cost reduction for catalysts preparation and the optimization of processing condition.

Key words: sugar alcohols, catalytic hydrogenolysis, propanediol, ethylene glycol
