ABSTRACT:
A process for the desulfurization of a hydrocarbon fraction having unsaturated hydrocarbons and sulfur compounds comprising the steps of contacting the hydrocarbon fraction with hydrogen gas and a fluorided platinum catalyst in the presence of an oxygen-containing hydrogenation moderator which is either water or an oxygen-containing material which is hydrogenatable to water and whose hydrogenation products will not poison the platinum catalyst. The oxygen-containing hydrogenation moderator should be present in sufficient quantity to substantially prevent the saturation of the unsaturated hydrocarbons without seriously affecting the desulfurization of the hydrocarbon fraction. A preferred oxygen-containing hydrogenation moderator is carbon monoxide.
