  • Process for the simultaneous selective hydrogenation of diolefins and nitriles
    Patent number: 5712415
    Abstract: A catalyst useful for the simultaneous and selective hydrogenation of diolefins and nitriles present in a hydrocarbon feedstock. The support material is preferably selected from the group consisting of an inorganic oxide-zeolite composite, carbon and zeolite. A catalytically active phase is deposited on the support material. The catalytically active metal phase is selected from the group consisting of partially reduced Group IB metals and completely reduced Group VIII metals. The catalytically active metal phase is present in an amount of .gtoreq.0.03 wt %. A process using the catalyst involves counter current flow of feedstock and hydrogen in the presence of the catalyst.
