"Additive composition suitable for reduction of CO emissions during regeneration of the catalyst in a process for cracking catalu00ectico fluid, composition of catalyst cracking fluid;Catalyst for cracking, and method for reducing the emission of CO during the cracking catalu00ectico fluid of a supply of hydrocarbon components with molecular weight in smaller ".It is a composition to control the emissions of CO and NOx in FCC processes comprising: (I) a acu00eddico oxide support, (II) oxide of cerium (III) oxide lantanu00eddeo,Except the cu00e9ria, such as praseodymium oxide (IV), optionally, oxide of a metal selected from groups IB and IIB, such as copper, silver and zinc, and (V) a precious metal such as Pt and PD.
