METHOD FOR CONVERTING HYDROCARBON FEEDSTOCK COMPRISING A SHALE OIL BY HYDROCONVERSION IN AN EBULLATING BED, FRACTIONATION BY ATMOSPHERIC DISTILLATION AND LIQUID/LIQUID EXTRACTION OF THE HEAVY FRACTION

摘要

Method for converting hydrocarbon feedstock comprising a shale oil, comprising a step of hydroconverting in an ebullating bed, a step of fractionating by atmospheric distillation into a light fraction, a naphtha fraction, a gas-oil fraction and a fraction heavier than the gas-oil fraction, a step of liquid/liquid extraction of the fraction heavier than the gas-oil fraction, and a dedicated hydrotreating for each of the naphtha and gas-oil fractions. The method aims to maximize the yield of fuel bases.
