Abstract
Disclosed is a method for preparing dual colloid catalyst compositions wherein a gel, or colloidal suspension is formed by admixing (a) a 0.6 to 10M aqueous solution containing one or more soluble salts or complexes of one or more transition metals, wherein at least one of the transition metals is reducible and hydrolyzable, and one or more elements selected from Cr, Al, Si, Th, U, the lanthanides, and elements from Groups IA and IIA of the Periodic Table of the Elements, with (b) a 0.5 to 10N aqueous base solution. The solid material is separated from the resulting gel, or colloidal suspension and washed and dried.
