| 20090221861 | Hydrogenation Process Using Catalyst Comprising Ordered Intermetallic Compound - The present invention relates to a process for the hydrogenation, in particular the selective hydrogenation of unsaturated hydrocarbon compounds using a hydrogenation catalyst comprising an ordered intermetallic compound. The ordered intermetallic compound comprises at least one metal of type A capable of activating hydrogen, and at least one metal of type B not capable of activating hydrogen, and the structure of the ordered intermetallic compound is such that at least one king of type A metals is mainly surrounded by atoms of the metal of type B. According to another aspect, the present invention is concerned with a catalyst comprising a support and the above ordered intermetallic compound supported on the support. According to still another aspect, the invention pertains to the use of a binary Pd—Ga ordered intermetallic compound as a catalyst. The hydrogenation process and catalysts of the present invention achieve a selectivity to the target compounds, e.g. in the selective hydrogenation of acetylene to ethylene, which is superior to the prior art. | 09-03-2009 |
| 20100261939 | Methods of Preparing, Optionally Supported, Ordered Intermetallic Palladium Gallium Compounds, the Compounds, as such, and Their Use in Catalysis - The present invention pertains to methods of preparing optionally supported, ordered intermetallic palladium gallium compounds, and the corresponding, optionally supported, intermetallic palladium gallium compounds obtainable by these methods. The present invention also pertains to the use of the optionally supported ordered intermetallic palladium gallium compounds as catalysts, such as in selective hydrogenations of alkynes, in particular ethyne, to give the corresponding alkenes. The optionally supported, ordered intermetallic palladium gallium compounds were found to be highly active and selective catalysts in the above hydrogenation reactions. | 10-14-2010 |
| 20100280295 | USE OF A MIXTURE OF AN ORDERED INTERMETALLIC COMPOUND AND AN INERT MATERIAL AS A CATALYST AND CORRESPONDING HYDROGENATION PROCESSES - The present invention relates to a process for the hydrogenation, in particular selective hydrogenation of at least one unsaturated hydrocarbon compound comprising reacting the at least one unsaturated hydrocarbon compound with hydrogen in the presence of a hydrogenation catalyst, wherein the hydrogenation catalyst comprises a mixture of an ordered intermetallic compound and an inert material. According to another aspect, the present invention is concerned with the use of a mixture of at least one ordered intermetallic compound and at least one inert material, as a catalyst. The mixtures for use as a catalyst in the present invention can be prepared easily and achieve a superior activity in relation to the prior art, while preserving the high selectivity to the target compounds, e.g. in the selective hydrogenation of acetylene to ethylene. | 11-04-2010 |
| 20120029254 | ORDERED COBALT-ALUMINUM AND IRON-ALUMINUM INTERMETALLIC COMPOUNDS AS HYDROGENATION CATALYSTS - The present invention relates to a process for the hydrogenation, in particular the selective hydrogenation of unsaturated hydrocarbon compounds, such as the selective hydrogenation of acetylene to ethylene, using a hydrogenation catalyst comprising an ordered intermetallic compound, namely an ordered cobalt-aluminum or iron-aluminum intermetallic compound. According to another aspect, the present invention relates to a catalyst comprising a support and at least one specific ordered cobalt-aluminum and/or iron-aluminum intermetallic compound supported thereon, as well as to the use of specific ordered intermetallic cobalt-aluminum and iron-aluminum intermetallic compounds as catalysts. The ordered cobalt-aluminum and iron-aluminum intermetallic compounds proved to be highly selective and long-term stable catalysts, e.g. in the selective hydrogenation of acetylene to ethylene in a large excess of ethylene. | 02-02-2012 |

| 20090216857 | METHODS OF PROVIDING PUBLISHED CONTENT - Methods of providing published content are presented. Content providers, including advertisers, can have their network addresses become black listed through no fault of their own. Content providers can utilize one or more intermediary providers each having their own distinct network address, possibly a registered domain name. An advertiser or other content provider can engage members of a distribution channel to disseminate promotional information to consumers where the promotional information comprises a network address of the intermediary provider. Upon a request directed toward the network address, the intermediary transforms published content obtained from the primary provider to make the content appear as though it originated from the intermediary provider. Should a black listing event occur, only the intermediary provider would be affected. An updated or new intermediary provider having a new, distinct network address can be instantiated to replace the black listed provider. | 08-27-2009 |
