Abstract
A process for hydrogenating hydrocarbons comprises admixing an aromatic hydrocarbon feed stock containing olefins and diolefins and boiling within a range of from C 5 hydrocarbons to 204 C., with hydrogen and a recycled hydrocarbon stream, hydrogenating diolefins contained in said admixture in a first reaction zone in the presence of a catalyst containing palladium, at a temperature within a range of from 93 to 260 C., passing the resulting effluent to a first separation zone, separating from said effluent a first gaseous fraction comprising hydrogen, and a first liquid fraction, returning a portion of said first liquid fraction to the reaction zone as said recycled hydrocarbon stream, passing the remainder of said first liquid fraction to a second separation zone, separating from said first liquid fraction a gasoline hydrocarbon product stream and an aromatic hydrocarbon concentrate, admixing at least a portion of said first gaseous stream with said aromatic hydrocarbon concentrate and passing the resulting admixture to a second reaction zone, therein hydrogenating olefins and sulfur compounds contained in said resulting admixture in the presence of a hydrodesulphurization catalyst, and recovering from the resulting reactor effluent an aromatic hydrocarbon product stream and a second gaseous fraction comprising hydrogen and hydrogen sulphide. Any remaining portion of the first gaseous stream may be recycled to the first reaction zone or withdrawn from the process. The palladium may be supported on alumina containing lithium. The catalyst in the second reaction zone may be nickel molybdate on alumina. There may be recycle of at least a portion of the second gaseous fraction to the second reaction zone.
