    Abstract: A process for the treatment of a gasoline comprising diolefins, olefins and sulphur-containing compounds including mercaptans: a) demercaptanization by addition of at least a portion of the mercaptans onto the olefins by bringing the gasoline into contact with at least one first catalyst; b) treatment of the gasoline obtained from a) with hydrogen in a distillation column comprising at least one reaction zone including at least one second catalyst. The operating conditions and the second catalyst of b) are selected such that in the distillation column, separation of the gasoline obtained from a) into a light gasoline fraction and a heavy gasoline fraction is carried out simultaneously with a reaction for thioetherification and selective hydrogenation of the diolefins of a gasoline fraction obtained from a) by contact with the second catalyst.

    Abstract: A process for treatment of gasoline comprising diolefins, olefins and sulphur-containing compounds including mercaptans. The process comprises: a) demercaptanization by addition of a portion of the mercaptans onto the olefins by bringing gasoline into contact with a first catalyst; b) separating the gasoline obtained from a) into a light gasoline cut and a heavy gasoline cut; c) introducing a stream of hydrogen and the second heavy gasoline cut obtained from b) into a distillation column comprising a reaction zone including a second catalyst in the sulphide form comprising a second support, a metal from group VIII and a metal from group VIb, to decompose the sulphur-containing compounds to form H2S; d) evacuating at a point located above the reaction zone at least one final light gasoline fraction comprising H2S, and at a point located below the reaction zone a desulphurized heavy gasoline fraction from the catalytic distillation column.
