Abstract
Abstract A process for the preparation of novel binder-containing titania supports, and catalyst compositions of improved porosity prepared from such supports, useful for Fischer-Tropsch synthesis. The supports are prepared by incorporating a small amount of an inorganic metal oxide binder, constituted of alumina, zirconia or silica, with titania. The catalysts are prepared by dispersing a catalytically effective amount of a metal, or metals, preferably cobalt, or cobalt plus an additional metal, or metals, catalytically active in a Fischer-Tropsch reaction on the titania binder support.
