Combined fluid catalytic cracking and hydrocracking process

摘要

An integrated combination of fluid catalytic cracking and hydrocracking select fractions of crude oil and FCC cycle oils to conserve hydrogen process requirements in the production of gasoline is discussed. Liquid products of hydrocracking are separated into low boiling components and a high boiling fraction is recycled to the FCC operation. Select fractions obtained from hydrocracking, FCC and crude oil distillation are upgraded by reforming and alkylation.
