  • Publication number: 20240359163
    Abstract: A method of preparing a catalyst support structure for use in a catalytic reaction. According to the method, a mixed metal oxide compound which defines a crystal lattice is synthesized. Cations of at least one catalytic promoter element are dispersed within the compound and incorporated into the crystal lattice. The conditions of synthesis are preselected to inhibit destabilization of the catalyst support structure such that the structure remains stable against collapse and exsolution under reaction conditions associated with the catalytic reaction. The metal oxide compound may comprise an oxidic perovskite having the formula A(1-x)A?(x)B(1-y)B?yO3 wherein A and B represent metal cations and A? and B? represent cations of the promoter element or elements. Also provided is a catalyst support structure having cations of a promoter element incorporated into its crystal lattice. The support structure is stable against collapse and exsolution under reaction conditions.

  • Patent number: 9029289
    Abstract: The present invention relates to a catalyst for preparing carboxylic acids and/or carboxylic anhydrides, which has a plurality of catalyst zones arranged in series and has been produced using a vanadium antimonate having a maximum content of crystalline valentinite of 5% by weight. The present invention further relates to a process for gas-phase oxidation in which a gas stream comprising at least one hydrocarbon and molecular oxygen is passed through a catalyst which has a plurality of catalyst zones arranged in series and has been produced using a vanadium antimonate having a maximum content of crystalline valentinite of 5% by weight.

  • Patent number: 8597598
    Abstract: A sample presentation device for radiation-based analytical equipment comprising a mounting base, a carrier carried by, and adjustable in position, relative to the mounting base, and an arm extending from the carrier and having at its opposite end a terminal member; Each of the carrier and terminal member has a coaxial connector for receiving two opposite end regions of a capillary tube that forms, in use, a reaction cell; A radiant heater, typically an infrared heater, is radially offset from the axis of the coaxial connectors for heating, in use, a capillary tube mounted by way of the coaxial connectors; The carrier and terminal member preferably have heaters associated therewith for heating the flow passages through them; The terminal member preferably has a passage generally coaxial with the connector for receiving a communications conductor carrying a temperature sensor at its end that is operatively located generally centrally within a capillary.

  • Publication number: 20130017125
    Abstract: A sample presentation device for radiation-based analytical equipment is provided comprising a mounting base, a carrier carried by, and adjustable in position, typically in the vertical direction, relative to the mounting base, and an arm extending from the carrier and having at its opposite end a terminal member. Each of the carrier and terminal member has a coaxial connector for receiving two opposite end regions of a capillary tube that forms, in use, a reaction cell. A radiant heater, typically an infrared heater, is radially offset from the axis of the coaxial connectors for heating, in use, a capillary tube mounted by way of the coaxial connectors. The carrier and terminal member preferably have heaters associated therewith for heating the flow passages through them as and when necessary.
