Abstract: Process for the selective hydrogenation of diolefinic compounds to monoolefinic compounds employing catalyst consisting essentially of elemental nickel on an inorganic support in the presence of hydrogen and at least one nitrogen-containing compound is disclosed. Selective hydrogenation of the less substituted of the two carbon-carbon double bonds of the diolefinic compound is achieved while isomerization of the more highly substituted, non-hydrogenated double bond, is minimized.

Abstract: Arsines are removed from gaseous stream, e.g., hydrocarbon or inert gas streams, comprising arsine impurities and also hydrogen sulfide, by contacting these gas streams with a sorbent material comprising copper oxide and zinc oxide. Preferably, the sorbent material is prepared by coprecipitating of hydroxides of copper and zinc and subsequent heating the hydroxides so as to convert the hydroxides to CuO and ZnO. Optionally, aluminum oxide is also present in the sorbent material.

Abstract: In one embodiment, an alkadiene and/or alkatriene is contacted with a free hydrogen containing gas in the presence of a catalyst composition comprising (a) palladium metal and (b) aluminum phosphate, so as to form primarily an alkene. In another embodiment, a cycloalkadiene and/or cycloalkatriene is contacted with a free hydrogen containing gas in the presence of a catalyst composition comprising (a) palladium metal and (b) aluminum phosphate, so as to form primarily a cycloalkene. The preferred cycloalkadiene is 1,5-cyclooctadiene, and the preferred cycloalkene is cyclooctene. Optionally, an alkali metal alkoxide, e.g. lithium methoxide, and/or carbon monoxide can be present during the hydrogenation reactions to improve the selectivity to alkenes and cycloalkenes, respectively.

Abstract: Metals contained in a hydrocarbon containing feed stream are at least partially removed by contacting the hydrocarbon containing feed stream under suitable demetallization conditions with hydrogen and a catalyst composition comprising an alumina-containing support and nickel arsenide, NiAs.sub.x. The life and activity of the catalyst composition can be increased by introducing a decomposable compound of a metal selected from the group consisting of the metals of Group IV-B, Group V-B, Group VI-B, Group VII-B and Group VIII of the Periodic Table into the hydrocarbon containing feed stream during or prior to contacting the feed stream with hydrogen and the catalyst composition. The preferred nickel arsenide catalyst composition is prepared by reduction of alumina-supported nickel arsenate with hydrogen gas.

Abstract: An improved process for removing metals from heavy oils and other hydrocarbon feed streams is disclosed. The process includes adding phosphorus sulfide to the hydrocarbon feed stream under suitable demetallizing conditions. It is believed that phosphorus sulfide reacts with the metals contained in the hydrocarbon containing feed stream to form oil insoluble compounds that can be removed from the hydrocarbon containing feed stream by any conventional method, such as filtration, centrifugation, or decantation.
