  • Publication number: 20240158706
    Abstract: The present invention relates to a process and a device for the treatment and separation of aromatic compounds starting from a gasoline feedstock, comprising the following stages/units: selective hydrogenation (A) of the gasoline feedstock (1) in the presence of hydrogen (2) in order to produce a selective hydrogenation effluent (3); fractionation (B) of the selective hydrogenation effluent (3) in order to produce at least a C5? cut (4) containing compounds having 5 or less carbon atoms and a C6+ cut (5) containing compounds having at least 6 carbon atoms; hydrogenation (C) of the C6+ cut (5) in order to produce a hydrogenation effluent (6); extraction of the aromatics (D) from the hydrogenation effluent (6) in order to produce at least an aromatic stream (17) concentrated in aromatic compounds and a raffinate (10) concentrated in non-aromatic compounds, with respect to the composition of the hydrogenation effluent (6).

  • Publication number: 20220325191
    Abstract: The present invention concerns a method for processing a petrol containing sulfur and olefin compounds, comprising the following steps: a) a step of hydrodesulfurisation in the presence of a catalyst comprising an oxide support and an active phase comprising a metal from group VIB and a metal from group VIII, b) a step of separating the H2S formed, c) a step of hydrodesulfurisation at a higher temperature than that of step a), with a hydrogen/feedstock ratio less than that of step a), and in the presence of a hydrodesulfurisation catalyst comprising an oxide support and an active phase consisting of at least one metal from group VIII, d) a step of separating the H2S formed.

  • Publication number: 20220325365
    Abstract: The present invention relates to a process for treating a lignocellulosic biomass pretreated beforehand (1), said process comprising the extraction of the free sugars from said pretreated biomass using an alcoholic or aqueous-alcoholic extraction solution (2), so as to obtain a liquid phase enriched in free sugars, called liquor (3), and a solid phase depleted in free sugars, called must (4).

  • Publication number: 20210261872
    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.
