ABSTRACT:
Hydrocarbon in a carrier of nitrogen or steam is passed over a devitalized supported noble metal/alkali or alkaline earth catalyst/absorber, such as Pt on an alumina monolith coated with potassium carbonate, which has sorbed NOx from engine exhaust to restore and regenerate the devitalized catalyst/absorber for reuse. The hydrocarbon undergoes a shift reaction to produce CO in situ which is the reactant gas for the regeneration.
