Abstract
A straight run naphtha is fractionated to yield on intermediate naphtha and the heaviest 10 vol % as heavy naphtha. The intermediate naphtha is catalytically reformed to yield reformed naphtha having a 90 vol % temperature (T90) of 310.degree. F. (155.degree. C.). The heavy naphtha is subjected to fluid catalytic cracking (FCC) to yield liquid fuel and lighter, including C.sub.4 olefins and a cracked naphtha having a research octane number suitable for gasoline blending.
