Patent ID: 7375169

Claim:
A method for polymerizing ethylene, comprising: preparing a supported catalyst composition comprising the steps of: (a) dehydrating a chromium impregnated support; (b) at least partially dissolving a titanium-containing compound in one or more inert solvents to provide a solution comprising the titanium-containing compound; (c) contacting the dehydrated chromium impregnated support with the titanium-containing solution to provide a mixture comprising the solvent, titanium-containing compound and chromium impregnated support; (d) removing the solvent from the mixture; and (e) activating the product of step (d) at a temperature of at least 800° F. (427° C.) to provide a supported titanated chrome catalyst composition; feeding the supported titanated chrome catalyst composition to a slurry reactor; and contacting the supported catalyst composition and an optional co-catalyst, under polymerization conditions within the slurry reactor, with ethylene.
