    Abstract: A xylene isomerization process includes introducing gas comprising hydrogen and a base to a reaction zone in which a catalyst comprising a Group VIII metal and a zeolite support resides. In one embodiment, the base may be formed in situ within the reaction zone from nitrogen and hydrogen that are introduced to the reaction zone. In another embodiment, the base is introduced directly to the reaction zone. The conditions in the reaction zone are effective to reduce the catalyst. A stream comprising C8 aromatics, e.g., xylenes and ethylbenzene may then be fed to the reaction zone containing the reduced catalyst. The reaction zone may be operated at conditions effective to isomerize the xylenes and hydrodealkylate the ethylbenzene. The xylene loss during the isomerization of the xylenes is lowered as a result of using the catalyst reduced in the presence of the gas comprising a base and hydrogen.

    Abstract: In an embodiment, a method of hydrogenating a highly unsaturated hydrocarbon to an unsaturated hydrocarbon includes contacting the highly unsaturated hydrocarbon with a catalyst in the presence of hydrogen. The catalyst comprises palladium and an inorganic support having a surface area of from about 4.5 to about 20 m2/g, or alternatively 5 to 14.5 m2/g. The inorganic support may comprise α-alumina treated with a fluoride source. The palladium may be primarily disposed near the surface of the support. In addition, the catalyst may comprise silver distributed throughout the support. In another embodiment, a method of making the foregoing selective hydrogenation catalyst includes contacting a fluorine-containing compound with an inorganic support, heating the support, and adding palladium to the inorganic support. After adding palladium to the support, the support can then be heated again, followed by adding silver to and then heating the support once again.

    Abstract: In some embodiments, methods of producing monoolefins include contacting an olefin stream with a polar solvent to extract a highly unsaturated hydrocarbon from the olefin stream, followed by contacting the polar solvent with a hydrogenation catalyst in the presence of hydrogen at conditions effective to hydrogenate the highly unsaturated hydrocarbon to a monoolefin. The monoolefin then desorbs from the polar solvent and enters the purified olefin stream, allowing the polar solvent to be recycled. In other embodiments, monoolefin production systems include an extraction-hydrogenation zone for performing the extraction and hydrogenating steps in situ. In alternative embodiments, the hydrogenation zone is disposed downstream from the extraction zone.

    Abstract: A catalyst composition is provided which can be used for hydrogenating a highly unsaturated hydrocarbon such as an alkyne or a diolefin. The catalyst composition contains palladium, a catalyst component of either silver or an alkali metal compound, or both silver and an alkali metal compound, and a metal aluminate catalyst support. Such metal aluminate catalyst support is prepared by a process of incorporating alumina with a metal component, preferably impregnating alumina with a melted metal component, to thereby provide a metal-incorporated alumina followed by drying and high temperature calcining to thereby provide a metal aluminate catalyst support. The catalyst composition disclosed can be used for hydrogenating a highly unsaturated hydrocarbon to a less unsaturated hydrocarbon. The process involves contacting a highly unsaturated hydrocarbon with a catalyst composition in the presence of hydrogen under a hydrogenation condition sufficient to effect a hydrogenation of the highly unsaturated hydrocarbon.
