Patent ID: 6977317

Claim:
A process for the selective hydrogenation of olefins contained in a hydrocarbonaceous feedstock comprising olefins and aromatic compounds which process comprises the steps of: (a) reacting the hydrocarbonaceous feedstock with hydrogen in a selective hydrogenation zone containing a catalyst comprising elemental nickel and an alumina support at olefin hydrogenation conditions including a temperature from about 20° C. (68° F.) to about 50° C. (122° F.), a pressure from about 618 kPa (75 psig) to about 7000 kPa (1000 psig) and a stoichiometric ratio of hydrogen to olefins from about 1:1 to about 5:1; and (b) recovering a hydrocarbonaceous product stream comprising aromatic compounds having a reduced concentration of olefins and containing less than 0.5 weight percent hydrogenated aromatic compounds.
