HIGH COBALT CONTENT, HIGH COBALT SURFACE AREA CATALYSTS, PREPARATION AND USE THEREOF

摘要

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