ABSTRACT:
Production of nickel/silica hydrogenation catalyst precursors by heating a slurry of particulate silica, e.g. kieselguhr, in an aqueous nickel ammine carbonate solution for a total period of at least 200 minutes at a pH above 7.5, followed by filtration, washing, drying, and optionally calcination.
