Process for the preparation of surface impregnated dispersed cobalt metal catalysts and hydrocarbon synthesis using said catalysts.

摘要

A process for the preparation of catalysts wherein a catalytically effective amount of cobalt is impregnated and dispersed as a film, or layer, on the peripheral outer surface of a particulate porous inorganic oxide support, notably alumina, silica, silica-alumina and titania; particularly titania. The catalysts are prepared by spraying a bed of the fluidized particular support particles with a liquid containing a dispersed or dissolved cobalt metal compound upon the support particles. The operation is performed at specified operating conditions. Novel catalyst particles having a thin film of catalytically-active metal in the outer layer only of the particle are described. Such particles are useful in synthesizing hydrocarbons from CO and H2 mixtures.
