O-208 Production of 1,3-Propandiol by hydrogenolysis of glycerol

Abstract

Glycerol hydrogenolysis was catalyzed by Pt/WO_3/ZrO_2 to give 1,3-propanediol (1,3-PD) in the yields up to 24 %. The catalytic activities and the selectivity toward 1,3-PD were remarkably affected by the type of support, loaded noble metal (NM) and the preparation/impregnation procedure. Controlled experiments show that the active site of catalyst for the formation of 1,3-PD may be the Pt over WO_3 supported on ZrO_2.
