  • Patent number: 8901028
    Abstract: A process for the complete or partial oxidation of hydrocarbons comprises contacting a C1-C8 hydrocarbon and hydrogen peroxide in the presence of a heterogeneous catalyst under conditions suitable to convert the C1-C8 hydrocarbon to at least one corresponding C1-C8 oxygenate product, wherein the heterogeneous catalyst provides confinement and contains both Brønsted-Lowry and Lewis acid centers. Particularly useful catalysts may include, for example, metal-modified ZSM-5 and other zeolites.
    Type: Grant
    Filed: June 25, 2010
    Date of Patent: December 2, 2014
    Assignee: University College Cardiff Consultants Limited

    Abstract: A process for the complete or partial oxidation of hydrocarbons comprises contacting a C1-C8 hydrocarbon and hydrogen peroxide in the presence of a heterogeneous catalyst under conditions suitable to convert the C1-C8 hydrocarbon to at least one corresponding C1-C8 oxygenate product, wherein the heterogeneous catalyst provides confinement and contains both Brønsted-Lowry and Lewis acid centers. Examples include zeolites modified with selected metals or metal oxides. Including copper, either in the catalyst, in a second catalyst of similar description, or as a homogeneous salt, increases both selectivity and activity of the process, particularly where an iron-containing catalyst is used.
