A cracking catalyst for promoting the oxidation of carbon monoxide to carbon dioxide during regeneration of the catalyst by the burning of coke therefrom, which comprises a crystalline aluminosilicate zeolite, an inorganic porous oxide matrix material and a CO oxidation promoter, such as a Group VII

A cracking catalyst for promoting the oxidation of carbon monoxide to carbon dioxide during regeneration of the catalyst by the burning of coke therefrom, which comprises a crystalline aluminosilicate zeolite, an inorganic porous oxide matrix material and a CO oxidation promoter, such as a Group VIII metal or compound thereof. The catalyst is preferably prepared by first supporting the CO oxidation promoter on an inorganic porous oxide base, such as alumina, and thereafter embedding the supported CO oxidation promoter and a crystalline aluminosilicate zeolite, such as rare earth metal exchanged Y-type zeolite, in an inorganic porous oxide matrix material, such as silica-alumina.
