Abstract: The nitrogen poisoning mechanism of FCC catalysts and the catalytic conversion of nitrogen-containing compounds are summarized. Based on this, the deleterious effects of nitrogen-containing compounds on catalytic cracking are analyzed and various technologies for direct catalytic cracking of high-nitrogen hydrocarbon feedstocks are reviewed.
