ABSTRACT:
Process for hydrocracking a petroleum hydrocarbon charge contaminated with nitrogenous compounds, comprising the hydrogenation of said charge in a first reaction zone followed with a separation in two phases, gaseous and liquid, of the resulting hydrogenated product, adding to said liquid phase the effluent from a subsequent prefractionation zone, treating the resulting mixture in a second reaction zone, adding to the effluent of said second reaction zone the above-mentioned gaseous phase, treating the resulting effluent in said prefractionation zone and separating therefrom a liquid fraction, at least one portion of which is recycled to said second reaction zone and a gaseous fraction which, after cooling is separated into a gas of high hydrogen content and a liquid effluent containing products converted in at least one reaction zone, said products being separated by fractionation.
