Abstract
A composition for promoting the oxidation of CO and minimizing NOx emissions during FCC processes comprises (i) acidic oxide support, (ii) at least one precious metal for promoting CO oxidation, and (iii) metals or metal oxides capable of reducing NOx production during CO oxidation, at least one precious metal (ii) being primarily distributed in the central interior of particulate additive and the metals or metal oxides (iii) being primarily distributed in the particulate additive as a shell around the precious metal.
