Abstract

BY USING A THREE-WAY CATALYST CONTAINING A METAL OXIDE, CO IS REMOVED AS CO//2 EVEN IN THE ″ RICH ″ REGION OF THE AIR/FUEL RATIO. IN ORDER TO ELUCIDATE THE MECHANISM OF THIS ACTION OF THE ADDED METAL OXIDE, THE REACTION OF CO WITH O//2 ON A PT-V//2O//5/AL//2O//3 CATALYST WAS INVESTIGATED USING A RECTANGULAR PULSE-REACTION APPARATUS. IN THE CO-O//2 REACTION ON A PT/AL//2O//3 CATALYST, A SIGNIFICANT AMOUNT OF UNREACTED CO WAS EXHAUSTED IN THE ″ RICH ″ REGION OF THE REACTANTS. FURTHERMORE, THE CONVERSION OF CO DECREASED MARKEDLY WITH ANINCREASE IN THE CO/O//2 RATIO IN THE REACTANTS. IN THE CO-O//2 REACTION ON THE PT-V//2O//5/AL//2O//3 CATALYST, ON THE OTHER HAND, THE CONVERSION OF CO WAS HIGH AND DID NOT DECREASE MARKEDLY WITH AN INCREASE IN THE CO/O//2 RATIO IN THE ″ RICH ″ REGION.
