摘要
Compositions comprising a component containing (i) an acidic oxide support, (ii) an alkali metal and/or alkaline earth metal or mixtures thereof, (iii) a transition metal oxide having oxygen storage capability, and (iv) a transition metal selected from Groups Ib and/or IIb of the Periodic Table or palladium are useful in FCC processes to reduce NOx emissions and/or to promote CO combustion while minimizing the formation of NOx. The acidic oxide support preferably contains silica alumina. Ceria is the preferred oxygen storage oxide.
