文摘

The multicomponent (Ni, Mo, and Cu) catalyst supported on kieselguhr was found to have ahigh activity for the hydrogenolysis of sucrose to produce industrially important glycerol, ethyleneglycol, propylene glycol, and sorbitol. The catalyst was characterized by scanning electronmicroscopy, X-ray diffraction, and surface area measurement. The presence of Ni is very commonin most of the catalysts used for this process. The presence of Mo and Cu promotes the activityof Ni when supported on kieselguhr. The concentrations of Ni, Mo, and Cu in the catalyst havebeen optimized to yield maximum glycerol during sucrose hydrogenolysis.
