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. The nitrogen scavenger is a particulate solid acid capable of sorbing pyridine at room temperature and retaining greater than about 5 weight percent of the sorbed pyridine after heating in a vacuum to about 300.degree. C. Examples of the nitrogen scavengers that can be used in the process include amorphous aluminosilicates, nonzeolitic molecular sieves such as pillared clays and delaminated clays, and zeolitic molecular sieves.
