This invention relates to a process for treatment of a gasoline that comprises diolefins, olefins and sulfur-containing compounds including mercaptans, consisting of a stage for treatment of the gasoline in a distillation column () comprising at least one reaction zone () including at least one catalyst that makes it possible to carry out the addition of mercaptans to the olefins that are contained in the gasoline that distills toward the top of the catalytic column.

Process for the production of a gasoline with a low sulfur content

The invention relates to the integration of a process for hydrotreatment of distillates (light and/or middle), that operates under a hydrogen partial pressure of 0.5 to 6.0 MPa, with a process for hydrotreatment/hydroconversion of middle and/or heavy distillates that operates at a hydrogen partial pressure that is at least 4.0 MPa higher than the hydrogen partial pressure of the process for hydrotreatment of distillates (light and/or middle). The integration resides in the use of the hydrogen-rich gas, obtained from the hydrotreatment/hydroconversion effluents, in the process for hydrotreatment of distillates (light and/or middle) and in the adjustment of the pressure level of this hydrogen-rich gas removed from the hydrotreatment/hydroconversion. This invention makes it possible to considerably reduce the net consumption of make-up hydrogen in the process for hydrotreatment of distillates (light and/or middle).

Process and apparatus for integration of a high-pressure hydroconversion process and a medium-pressure middle distillate hydrotreatment process, whereby the two processes are independent

Process for treatment of a feedstock, such as hydrocarbons that comprise at least 4 carbon atoms per molecule and that comprise at least one unsaturated compound including benzene, such that said feedstock is treated in a distillation zone, associated with a hydrogenation reaction zone, at least in part outside of the distillation zone, and an isomerization zone, so as to discharge&#x2014;at the top of the distillation zone and at the bottom of the distillation zone&#x2014;an effluent that is low in unsaturated compounds, whereby said process comprises the treatment of at least a second feedstock, comprising at least one unsaturated compound including benzene, at least partially directly injected into the hydrogenation zone that is outside of the distillation zone.

Process for selective reduction of the contents of benzene and light unsaturated compounds of different hydrocarbon fractions
