PROCEDE DE CONVERSION DE CHARGE HYDROCARBONEE COMPRENANT UNE HUILE DE SCHISTE PAR HYDROCONVERSION EN LIT BOUILLONNANT, FRACTIONNEMENT PAR DISTILLATION ATMOSPHERIQUE, ET HYDROCRAQUAGE

摘要

Method and plant for converting hydrocarbon feedstock comprising a shale oil, comprising a step of hydroconverting in an ebullating bed, a fractionation into a light fraction, a naphtha fraction, a gas-oil fraction and a fraction heavier than gas-oil, the naphtha and gas oil fraction being hydrotreated, the fraction heavier than gas oil being hydrocracked, the products of the hydrocracking being sent to the step for hydrotreating. The method aims to maximize the yield of fuel bases.
