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.
A process for the hydrogen desulfurization of a hydrocarbon fraction comprising olefinic, aromatic and sulfur compounds comprising the step of contacting said hydrocarbon fraction with hydrogen gas and a fluorided platinum catalyst in the presence of an oxygen-containing hydrogenation moderator selected from the group consisting of water, and oxygen-containing materials which are hydrogenatable to water and whose hydrogenation products will not poison the platinum catalyst, said hydrogenation moderator being present in a quantity sufficient to minimize the saturation of the olefinic and aromatic compounds by the hydrogen gas and the fluorided catalyst.
