A hydrocarbon feed conversion method and device comprising a shale oil, comprising a bubbling bed hydroconversion stage, fractionation into light fractions, naphtha, diesel fuel and heavier than diesel fuel, the naphtha and diesel fractions being hydrotreated, the fraction plus heavy diesel fuel being hydrocracked, the products of the hydrocracking being returned to the hydrotreating step. The process aims to maximize the yield of fuel bases. |
