Heavy naphtha conversion process

摘要

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 DEG F. (155 DEG C.). The heavy naphtha is subjected to fluid catalytic cracking (FCC) to yield liquid fuel and lighter, including C4 olefins and a cracked naphtha having a research octane number suitable for gasoline blending.
