  • Catalyst or sorbent beds
    Patent number: 7323152
    Abstract: A fixed bed containing a particulate catalyst or sorbent material (10) subject to operation at high temperature having a shaped boundary member (16) inclined to the direction of fluid flow through the bed that maintains the depth of said catalyst or sorbent at the boundary of the bed through a series of thermal expansion-thermal contraction cycles is described. By maintaining bed depth, the shaped boundary member (16) can prevent bypass of, e.g. ammonia through a bed of particulate ammonia oxidation catalyst.
    Type: Grant
    Filed: July 3, 2002
    Date of Patent: January 29, 2008
    Assignee: Johnson Matthey PLC
    Inventors: Sean Alexander Axon, Andrew Mark Ward, Alan Bruce Briston
  • PRODUCTION OF BONE MORPHOGENIC PROTEINS (BMPs) IN TRANSGENIC MAMMALS
    Publication number: 20070056050
    Abstract: The present invention provides materials and methods for the production of recombinant BMPs in transgenic animals. In particular, the invention provides materials and methods for the production of recombinant BMPs in the milk of transgenic animals that express recombinant BMPs in the mammary gland.

  • Spinel based high temperature shift catatalysts
    Publication number: 20040266614
    Abstract: A method is described for producing a high temperature shift catalyst, not requiring a reduction step prior to use, by precipitating a composition containing divalent and trivalent iron compounds and a modifier metal selected from trivalent chromium and/or manganese compounds from an aqueous solution containing iron and modifier metal salts with a base, and forming the resultant precipitate into shaped catalyst units, without exposing said precipitate to an oxidising atmosphere at temperatures above 200° C.

  • Ammonia oxidation
    Publication number: 20040170553
    Abstract: Ammonia oxidation by passing a mixture of air and ammonia over a catalyst containing at least one cobalt compound at an elevated temperature wherein, prior to contact with the catalyst, the air is passed through an absorber comprising a support carrying an absorbent material for acidic gases.

  • Process for the production of aromatic amines
    Publication number: 20010020115
    Abstract: Process for the production of an aromatic amine by reacting an aromatic hydrocarbon with ammonia at a temperature of less than 500° C. and a pressure of less than 10 bara in the presence of a catalyst comprising at least one metal selected from the group consisting of the transition elements, lanthanides and actinides, preferably in the presence of an oxidant.
