Abstract: A process for hydrogenating highly unsaturated hydrocarbons to less unsaturated hydrocarbons wherein production of saturated hydrocarbons is minimized. The process utilizes catalyst including Ce2O3, MgO, and an inorganic support, and optionally palladium, optionally silver, and/or an optional alkali metal.

Abstract: Processes and an apparatus for hydrogenating highly unsaturated hydrocarbons contained in an effluent stream to an unsaturated hydrocarbons or isomerizing the highly unsaturated hydrocarbons to other highly unsaturated hydrocarbons are provided. The effluent stream is contacted with a guard bed to remove at least a portion of impurities contained within the process stream and to isomerize at least a portion of the highly unsaturated hydrocarbons. In an aspect, the guard bed comprises a solid sulfur adsorption/isomerization catalyst composition. In an aspect, the effluent stream is contacted with a catalyst that comprises an inorganic support, palladium, and silver.

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.

Abstract: An apparatus and a method for injecting an antifoulant has been developed for suppressing coke formation during pyrolysis in a cracking furnace. The apparatus and method result in the antifoulant being atomized and vaporized, which is critical for proper distribution of the antifoulant. The proper distribution of the antifoulant through this novel apparatus and method results in longer runtime and higher efficiencies for cracking furnaces.

Abstract: A process of making a metal aluminate catalyst support by incorporating, preferably impregnating, alumina, preferably gamma alumina, with a metal component to thereby provide a metal-incorporated alumina which is then calcined under a calcining condition to thereby provide a metal aluminate catalyst support. Such calcining condition includes a temperature in the range of from about 600° C. to about 1350° C. Preferably the metal component has been melted under a melting condition to thereby provide a melted metal component.
