NPRA (National Petroleum Refiners Association) Q and A--1. Refiners probe FCC (fluid catalytic cracker) feedstock capabilities
Questions and answers (Q and A) reported from an NPRA session (Dallas 10/10-13/78) covered excessive coke formation with North Slope heavy gas oils; the recycling of heavy catalytic naphtha or raffinate from aromatics extraction of thermally cracked naphthas to increase the refinery gasoline pool octane number; FCC straight-run gasoline fractions to increase octane number; the effect on FCC unit yields of charging stocks in the 650/sup 0/F and 450/sup 0/F boiling range; the use of leaded gasoline slops and atmospheric residue as an FCC feed; parameters justifying FCC feed hydrotreating; hydrotreating a portion of cycle stock and using the product as an FCC feed; and controlling regeneration with a catalyst or feed that produces low coke yields in a riser cracker.
