  • Patent number: 8288311
    Abstract: A process and catalyst for the hydro-oxidation of an olefin having three or more carbon atoms, such as propylene, to form an olefin oxide, such as propylene oxide. The process involves contacting the olefin with oxygen in the presence of hydrogen and a hydro-oxidation catalyst under reaction conditions; the catalyst comprising gold nanoparticles deposited on a nanoporous titanium-containing support, prepared by depositing a gold-ligand cluster complex onto the support to form a catalyst precursor, and then heating and/or chemically treating the catalyst precursor to form the hydro-oxidation catalyst composition. The hydro-oxidation catalyst exhibits stabilized catalyst activity, enhanced lifetime, and improved hydrogen efficiency.

  • Publication number: 20120083540
    Abstract: This invention relates to a method for the preparation of a hydrocarbon synthesis catalyst material, in the form of a hydrocarbon synthesis catalyst precursor and/or catalyst, preferably, a Fischer Tropsch synthesis catalyst precursor and/or catalyst. The invention also extends to the use of a catalyst precursor and/or catalyst prepared by the method according to the invention in a hydrocarbon synthesis process, preferably, a Fischer Tropsch synthesis process. According to this invention, a method for the preparation of a hydrocarbon synthesis catalyst material includes the steps of treating Fe(II) carboxylate in solution with an oxidising agent to convert it to Fe(III) carboxylate in solution under conditions which ensure that such oxidation does not take place simultaneously with any dissolution of Fe(0); and hydrolysing the Fe(III) carboxylate solution resulting from step (iii) and precipitating one or more Fe(III) hydrolysis products.
