The effect of basic feedstock components on product slate from a bench scale fluid catalytic cracking (FCC) unit was studied. Basic compounds were isolated from 650{degrees}-1000{degrees}F and >1000{degrees}F boiling ranges of Wilmington, CA, crude oil. These basic concentrates were added in varying amounts to a conventional gas oil FCC feedstock; the resulting mixtures were cracked at 970{degrees}F and a catalyst/oil ratio near 8.5. Balances for total mass, sulfur, and nitrogen over gaseous, liquid, and solid (coke) products were determined for each FCC run. The reduction it gasoline yield from adding basic components resulted partly from a dilution effect, and partly from a catalyst inhibition effect for selected types of basic components. Basic nitrogen compounds boiling between 650{degrees} and 1000{degrees}F inhibited catalytic activity to a much greater extent than >1000{degrees}F bases. Higher boiling bases (>1000{degrees}F) primarily formed coke during FCC. Sulfur and/or oxygen-containing basic types (e.g., sulfoxides) exhibited minimal catalyst poisoning properties and may in fact have lessened catalyst inhibition by basic nitrogen compounds.
