ABSTRACT:
A cracking catalyst for promoting the oxidation of carbon monoxide to carbon dioxide during regeneration of the catalyst by the burning of coke therefrom, comprises two distinct crystalline aluminosilicate zeolite particles embedded in an inorganic porous oxide matrix material. The first zeolite is the ultra-stable variety of Y-type zeolite which contains a CO oxidation promoter, such as a Group VIII metal or compound thereof. The second zeolite is a rare earth metal-containing zeolite. A preferred catalyst comprises an ultra-stable Y-type zeolite containing Pt and/or Pd and a rare earth metal exchanged X- or Y-type zeolite, which zeolites are embedded in a silica-alumina or clay matrix.
