Abstract: A process for treating a gasoline containing sulfur compounds, olefins and diolefins comprises step a) bringing into contact the gasoline, hydrogen and a hydrodesulfurization catalyst, in at least one reactor. In step b) effluent from a), hydrogen, and a hydrodesulfurization catalyst are brought into contact in at least one reactor. In step c) effluent from b) is sent to a separation drum operating at a pressure of between 1.0 and 2.0 MPa to obtain a gaseous fraction containing H2S and hydrogen and a liquid fraction containing desulfurized gasoline and a fraction of dissolved H2S. In step d), the liquid fraction is sent to a stabilization column to obtain at the top a stream comprising residual H2S and C4- hydrocarbon compounds and at the bottom a stabilized gasoline. In step e), the gaseous fraction is recycled at least in part to at least one of steps a) and/or b).

Abstract: Process for producing a light gasoline having a sulfur content of less than 10 ppm by weight, with respect to the total weight of the light gasoline, starting from a gasoline containing sulfur compounds, olefins and diolefins, which process includes a) a stage of selective hydrogenation to hydrogenate the diolefins and a reaction for increasing the molecular weight of a part of the sulfur compounds; b) a stage separating the effluent obtained from stage a) into a gaseous fraction, a light gasoline cut and a heavy gasoline cut, stage b) being carried out in a fractionation column containing n plates, n being an integer of 20 or more, the first plate being the reboiler and the plate “n” being the condenser, wherein the light gasoline cut is withdrawn from the fractionation column at the plate “n-i”, with i being 1 to 10.

Abstract: A two-step hydrocracking process with a distillation step wherein a dividing wall distillation column is used, the dividing wall dividing the lower part of the column into two compartments, located in the section of the column located under the supply of said column with the unconverted effluent resulting from the first hydrocracking step. The distillation column is fed on either side of the vertical dividing wall with the liquid hydrocarbon effluent from the first hydrocracking step and with the liquid hydrocarbon effluent from the second hydrocracking step, allowing the concentration of the HPNAs contained in the effluent from the second hydrocracking step in a specific compartment of the column delimited by the dividing wall and avoiding the dilution of said HPNAs by the unconverted effluent from the first hydrocracking step. The present invention allows purging of purer HPNAs.
