Abstract:
1. A process for desulphurizing a gasoline cut containing olefins, sulphur-containing compounds and optionally molecules from C3 and C4 cuts, comprising at least: a first step A for contacting said gasoline cut with an acidic resin producing higher boiling point sulphur-containing compounds by an addition reaction between the olefins and sulphur-containing compounds of said gasoline cut; a step B for fractionation of resultant gasoline cut containing reaction product from the first step to produce a light fraction the sulphur content of which is reduced with respect to the feed, and a higher boiling point fraction which concentrates the sulphur-containing compounds; in which the resin used in step A has an acid capacity of more than 4.7 equivalents per kg, a specific surface area of less than 55 m 2 /g and a pore volume in the range of 0.16 ml/g to 0.25 ml/g.
