ABSTRACT:
Catalytic cracking processes are improved by employing cracking catalyst particles containing rare earth components spray impregnated thereon. In comparison to other rare earth-promoted cracking catalysts, the cracking catalysts of the invention exhibit greater activity for oxidizing carbon monoxide to carbon dioxide during the regeneration step of the cracking process wherein coke-containing catalyst particles are reactivated for cracking hydrocarbons by combustion of the coke.
