Compositions and processes 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 particles of a zeolite having a pore size ranging from about 3 to about 7.2 Angstoms and a SiO2 to Al2O3 molar ratio of less than about 500. Preferably, the NOX reduction composition contains NOX reduction zeolite particles bound with an inorganic binder In the alternative, the NOX , reduction zeolite particles are incorporated into the cracking catalyst as an integral …
