Abstract:

The recent progress of catalysts used in hydrogenolysis of glycerol to propanediols is reviewed. Catalyst is the key factor in the hydrogenolysis of glycerol to propanediols，such as Cu，Ru，Rh，Pt，Ni，Co-based catalysts. The catalyst properties，product separation and environment pollution are influenced by the catalyst type，composition，vector，preparation and process condition. There is still a lack of fundamental understanding of high activity and selectivity catalyst in hydrogenolysis of glycerol to 1,3-propanediol，Optimization of preparation technologies of catalysts used in hydrogenolysis of glycerol to 1,2-propanediol will be needed in order to achieve commercialization.
