Process for the catalytic cracking of feedstocks containing nitrogen

Hydrocarbon feedstocks containing relatively high levels of nitrogen contaminants are converted by catalytic cracking to products of lower average molecular weight by contacting the feedstock with a mixture of a cracking catalyst and separate particles of a nitrogen scavenger comprising microporous...

Beschreibung
Zusammenfassung:	Hydrocarbon feedstocks containing relatively high levels of nitrogen contaminants are converted by catalytic cracking to products of lower average molecular weight by contacting the feedstock with a mixture of a cracking catalyst and separate particles of a nitrogen scavenger comprising microporous solids selected from the group consisting of acid clays; hydrogen or ammonium exchanged mordenite, clinoptilolite, chabazite and erionite; mineral acids or mineral acid precursors supported on an inorganic, refractory oxide; and Catapal alumina.
