    Abstract: Compositions for reduction of NOx generated during a catalytic cracking process, preferably, a fluid catalytic cracking process, are disclosed. The compositions comprise a fluid catalytic cracking catalyst composition, preferably containing a Y-type zeolite, and a particulate NOx reduction composition containing ferrierite zeolite particles. Preferably, the NOx reduction composition contains ferrierite zeolite particles bound with an inorganic binder. In the alternative, the ferrierite zeolite particles are incorporated into the cracking catalyst as an integral component of the catalyst. NOx reduction compositions in accordance with the invention are very effective for the reduction of NOx emissions released from the regenerator of a fluid catalytic cracking unit operating under FCC process conditions without a substantial change in conversion or yield of cracked products. Processes for the use of the compositions are also disclosed.
