Estimating the term…
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.
A process of making a catalyst composition comprising impregnating a metal aluminate catalyst support with palladium and a catalyst component selected from the group consisting of silver and an alkali metal compound wherein said metal aluminate catalyst support is prepared by a process comprising:
A process of making a catalyst composition comprising impregnating a metal aluminate catalyst support with palladium and a catalyst component selected from the group consisting of silver and an alkali metal compound wherein said metal aluminate catalyst support is prepared by a process comprising:
A catalyst composition comprising palladium, a metal aluminate catalyst support, and a catalyst component selected from the group consisting of silver and an alkali metal compound wherein said metal aluminate catalyst support comprises a metal aluminate and alumina and further wherein said alumina is selected from the group consisting of alpha alumina, beta alumina, delta alumina, eta alumina, gamma alumina and combinations thereof and further wherein said metal aluminate catalyst support has been calcined under a calcining condition wherein said calcining condition comprises a temperature in the range of from about 1100° C. to about 1350° C.
