REDISPERSION OF COBALT METAL PARTICLES IN Co/TiO2 CATALYST AND ITS EFFECT ON PROPENE HYDROGENATION

Article abstract of DOI:10.1246/cl.1983.265

The rate of propene hydrogenation on Co/TiO2 catalyst, prepared by an alkoxide technique, was significantly enhanced when the catalyst was reduced by hydrogen at 700 deg C.However, over the catalyst prepared by an usual impregnation method, the enhancement of the rate was not observed at any reduction temperatures.The effects of reduction temperatures on the rate of propene hydrogenation were elucidated by redispersion of metallic cobalt particles.
