Kinetic study on reaction mechanism of hydrogenolysis over Pt/WO3/Al2O3 catalysts

摘要

The hydrogenolysis is one of the useful reactions to produce diols. Recently we have reported that the perimeter interface between WO3 domains and γ-Al2O3 has an important role in selective hydrogenolysis of glycerol to 1,3-propanediol (PDO) . 1,3-PDO which is valuable chemical was formed with high selectivity, however, 1,2-PDO and 1-PrOH were also produced as by-products. In this study, to get the fundamental knowledge about controlling the dissociation position of C-O bond, the hydrogenolysis mechanisms of diols (with/without vicinal OHs) were investigated.
