ABSTRACT:
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.
