  • Publication number: 20130327682
    Abstract: Method and plant for converting hydrocarbon feedstock comprising a shale oil, comprising a step of decontaminating, a step of hydroconverting in an ebullating bed, a step of fractionating into a light fraction, a naphtha fraction, a gas-oil fraction and a fraction heavier than the gas-oil fraction, the naphtha and gas-oil fractions being hydrotreated, the fraction heavier than the gas-oil fraction being conveyed to the decontaminating step. The method aims to maximize the yield of fuel bases.

  • Publication number: 20130319911
    Abstract: 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.

  • Publication number: 20130319908
    Abstract: 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.
