Ferrierite compositions for reducing nox emissions during fluid catalytic cracking

Abstract From the Canadian patent

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 ferricrite 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 …
