    摘要: Process for desulfurization of an effluent for cracking or steam-cracking hydrocarbons, more particularly a gasoline for example for catalytic cracking that comprises the elimination of thiophenic compounds by alkylation of these compounds, followed by a distillation, a hydrocracking of said alkyl-thiophenic compounds, then a hydrodesulfurization of the effluent that is obtained from the hydrocracking zone. In a preferred embodiment, this process comprises a preliminary stage for separating the cracking or steam-cracking effluent into three fractions, and proposes sending to the alkylation stage only the intermediate fraction that is low in heavy basic nitrogen-containing compounds that are initially present in the effluents that are to be alkylated.

    摘要: A novel process is described which allows selective hydrodesulphurizing gasoline cuts containing sulphur-containing compounds and olefins. The process employs a catalyst comprising a support selected, for example, from refractory oxides such as aluminas, silicas, silica-aluminas or magnesia, used alone or as a mixture, a group VI metal, preferably Mo or W which may or may not be promoted by a group VIII metal, Co or Ni. The catalyst is characterized by a mean pore diameter of more than 22 nm. The process may comprise one or more steps.

    摘要: The invention relates to a process for the hydrotreatment of an olefinic gasoline comprising at least one selective hydrogenation stage, and generally of simultaneous conversion of mercaptans by weight increase, in which the makeup hydrogen used in this stage or these stages has a reduced CO+CO2 content, preferably comprised between 5 and 200 ppmv. Most often, the CO content is comprised between 1 and 20 ppmv. The process typically makes it possible to hydrorefine an olefinic gasoline by more or less eliminating the diolefins and sulphur compounds.
