Process for desulphurizing gasoline by converting sulphur-containing compounds to higher boiling point compounds

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 m2/g and a pore volume in the range of 0.16 ml/g to 0.25 ml/g.
