Hydrogenolysis of glycerol to 1,2-propanediol on the high dispersed SBA-15 supported copper catalyst prepared by the ion-exchange method

摘要

The catalytic properties of supported Cu/SBA-15 catalysts prepared by the ion-exchange method were investigated for the hydrogenolysis of glycerol in a fixed-bed tubular reactor. The Cu/SBA-15 catalyst performed higher selectivity to 1,2-propanediol and high stability. We propose that the larger specific surface area and the ordered mesoporous channels of SBA-15 may play important roles in stabilizing highly dispersed copper species, and forming an active and durable catalyst for the title reaction.
