A PROCESS FOR THE FISCHER -TROPSCH SYNTHESIS OF HYDROCARBONS USING HIGH COBALT CONTENT, HIGH COBALT SURFACE AREA CATALYSTS

摘要

A particulate catalyst is described comprising an intimate mixture of cobalt and aluminum compounds having cobalt and aluminum at an atomic ratio in the range 10:1 to 2:1 (C0:A), which when reduced at 425°C, has a cobalt surface area as measured by hydrogen chemisorptions at 150°C of at least 30 m2/g of catalyst. The catalyst is prepared by sequential precipitation of cobalt with aluminum ions in the presence of an alkaline precipitation agent. The catalyst may be used for the hydrogenation of unsaturated compounds or the Fischer-Tropic synthesis of hydrocarbons.
