A process for regeneration of cracking catalyst while minimizing NO.sub.x emissions is disclosed. A zinc-based DeNO.sub.x catalyst is present in an amount and in a form which reduces NO.sub.x emissions. Relatively small amounts of zinc oxides impregnated on a separate support having little or no cracking activity are preferred. The zinc NO.sub.x reduction catalyst can be a separate particle additive, or can be made in situ by adding a solution or dispersion of zinc or a compound thereof to the cracking unit, or to the hydrocarbon feed to the cracking unit.
