Abstract
The invention relates to a process for treating heavy petroleum feedstocks for producing a gas oil fraction that has a sulfur content of less than 50 ppm and most often 10 ppm that includes the following stages: a) ebulliated-bed catalytic hydrocracking, b) separation from hydrogen sulfide of a distillate fraction that includes a gas oil fraction and a heavier fraction than the gas oil, c) hydrotreatment of said distillate fraction, and d) separation of a gas oil fraction with less than 50 ppm of sulfur. Make-up hydrogen, preferably all make-up hydrogen, is to stage c). Advantageously, the heavier fraction from step (b) is subjected to catalytic cracking. The invention also relates to an installation that can be used for implementing this process.
