Abstract
Olefin oxidation catalysts having improved attrition resistance are produced by incorporating a substantially uniform-appearing coating of a partially calcined catalytic material onto an inert porous support containing sorbed aqueous silica sol and then completing the calcination of the catalyst. Such catalysts are useful in a variety of exothermic chemical processes, including vapor phase oxidation of olefinically unsaturated hydrocarbons to the corresponding unsaturated aldehydes, especially propylene to acrolein.
