ABSTRACT:
A method for the removal of CO from flue gas which comprises contacting a spent noble metal reforming catalyst with flue gas from a cat cracker regenerator at 1000.degree.-1350.degree. F. to effectively oxidize CO to CO.sub.2. The spent catalyst while no longer efficient in a reforming process is found to be effective in reducing the CO level to a concentration range of 5000 parts per million and less.
