  • Patent number: 7875742
    Abstract: The present invention is directed to a process for hydrogenating one or more organic compounds especially unsaturated organic compounds by bringing the compound into contact with a hydrogen-containing gas in the presence of a catalyst, which comprises one or more catalytically active metals applied to a porous catalyst support. The one or more catalytically active metals having been derived via a decomposed organic complex of the metal on the support, in particular amine complexes of the metal. The decomposed complex may be treated with hydrogen to activate the catalyst before use as a hydrogenation catalyst.

  • Patent number: 7799210
    Abstract: A three-step process of removing sulfur from naphtha feeds. The steps include a first hydrotreating step, a mercaptan removal agent and an adsorbent containing a reactive metal on an inorganic support. Step one removes at least 95 wt. % of the sulfur compounds while preserving at least 50 wt. % of the olefins. Treatment with the mercaptan removal agent lowers the sulfur content to 30 wppm total sulfur and final naphtha product contains leas than 10 wppm total sulfur.

  • Patent number: 7686948
    Abstract: The use of one or more alkali metals, preferably sodium, to remove sulfur from hydrocarbon streams containing up to about 100 wppm sulfur. The hydrocarbon stream is introduced into a reactor where it is contacted with one or more alkali metals. The treated hydrocarbon stream is then subjected to a water wash thereby resulting in an aqueous phase fraction and a hydrocarbon phase fraction. The aqueous phase fraction, which is separated from the hydrocarbon phase fraction contains water-soluble sodium moieties.

  • Patent number: 7605107
    Abstract: This invention relates to supported multi-metallic catalysts for use in the hydroprocessing of hydrocarbon feeds, as well as a method for preparing such catalysts. The catalysts are prepared from a catalyst precursor comprised of at least one Group VIII metal and a Group VI metal and an organic agent selected from the group consisting of amino alcohols and amino acids. The catalyst precursor is thermally treated to partially decompose the organic agent, then sulfided.

  • Patent number: 7547805
    Abstract: The present invention relates to a process for the production of severely sterically hindered amino-ether alcohols using a catalyst based on the combination of one or more catalytically active metals supported in a dispersed form on one or more ordered mesoporous materials as support.

  • Patent number: 7507327
    Abstract: Refractory or hard sulfur found in a hydrocarbon stream containing refractory sulfur heterocycle compounds, particularly those exhibiting steric hindrance, is removed from the stream by contacting it with a sodium reagent comprising a sodium component, having free sodium, supported on a solid support component. If the hydrocarbon stream contains more labile or easy sulfur, then it is treated, typically by hydrodesulfurization, to remove at least most of the labile sulfur before it is contacted with the sodium reagent. This is useful for bringing the sulfur level of middle distillate fuel streams, such as diesel and jet fuel fractions, down to a level of less than about 10 wppm, employing conventional hydrodesulfurizing catalysts and conditions.

  • Patent number: 7442840
    Abstract: The present invention relates to a process for preparing severely sterically hindered secondary amine ether alcohols and diamine polyalkenyl ethers by reacting a primary amino compound with a polyalkenylether glycol in the presence of a high activity nickel powder hydrogenation catalyst which is marked by high conversion of reactants and increased selectivity to desired final product.

  • Publication number: 20060166809
    Abstract: The present invention is directed to processes for preparing supported metal catalysts comprising one or more catalytically active metals applied to a porous catalyst support and to processes that use such catalysts. The process requires the formation of an organic complex during the manufacture of the catalyst which after its formation is either partially or fully decomposed before reduction if the metal to form the catalyst. The catalysts have high levels of metal dispersion and uniform distribution of catalytically active metals on the support. The catalysts obtained form the processes are particularly effective in catalysing Fischer-Tropsch reactions and as adsorbants for the removal or organosulfur compounds from hydrocarbons.
