  • Catalyst and process
    Patent number: 8945497
    Abstract: The invention concerns a process for the oxidation of organic compounds contained in a gas stream and comprises the step of introducing the gas stream containing the organic compounds together with sufficient oxygen to effect the desired amount of oxidation into an oxidation reactor containing an oxidation catalyst and maintaining the temperature of said gas stream at a temperature sufficient to effect oxidation, characterised in that the oxidation catalyst contains at least 0.01% by weight of ruthenium, cobalt or manganese.
    Type: Grant
    Filed: September 17, 2009
    Date of Patent: February 3, 2015
    Assignee: Johnson Matthey PLC
    Inventors: Gareth Headdock, Kenneth George Griffin, Peter Johnston, Martin John Hayes

  • Catalyst
    Patent number: 7375049
    Abstract: A catalyst suitable for the dehydrogenation and hydrogenation of hydrocarbons comprises at least one first metal and at least one second metal bound to a support material. The at least one first metal comprises at least one transition metal, suitably a platinum group metal. The support material is provided with an overlayer such that acidic sites on the support material are substantially blocked. In a preferred embodiment the catalyst is also substantially chloride free. Method of preparing catalyst are also disclosed.
