ATTRITION-RESISTANT CATALYST COMPOSITION, METHOD OF MAKING AND USE

摘要

A method is disclosed for preparing titania-containing catalysts and catalyst supports that are fluidizable and attrition-resistant. By the method, a fluidizable substrate is impregnated with titanyl sulfate or a related compound. The compositions may be used to advantage in applications requiring titania-bearing catalysts or titania supports and are particularly useful in preparing fluid bed catalysts for the oxidation of o-xylene and naphthalene to phthalic anhydride.
