Fremstilling og anvendelse av Fischer-Tropsch type hydrokarbonsyntesekatalysator

摘要

Catalysts useful for Fischer-Tropsch hydrocarbon synthesis are prepared by adding an aqueous solution of a carbonate salt to an aqueous solution of one or more catalytic metal component salts, under mixing conditions, to form a slurry containing a hydroxy metal carbonate precipitate of the catalytic metal. This slurry is heated to drive off CO2 and change the nature of the hydroxy metal precipitate and form a second precipitate which is composited with the zeolite component of the catalyst. The composite, which may also contain promoter metals and other components, is dried to a moisture content of from 6 to 15 wt. % and then reduced in hydrogen to form the catalyst.
