摘要

Desulfurization of a gasoline fraction (I) containing olefins, sulfur compounds and optionally 3-4 carbon fractions, comprises contacting (I) on an acidic resin and allowing the reaction of olefins and sulfur compounds to produce heavy sulfur compounds, fractionating the obtained mixture to produce a light fraction with decreased sulfur content compared to the load, and a heavy fraction containing concentrated sulfur compounds, where the resin has an acidity greater than 4.7 equivalents per kg, and a specific surface area less than 55 m 2/g.
