  • Spherical catalyst supports
    Patent number: 8946117
    Abstract: There is presented a catalyst support that has a substantially spherical body, penetrated with a plurality of tunnels extending from a first end on a surface location of the catalyst body to another end on another surface location of the body. The support is made of alumina or like composition. The catalyst body has a total surface that includes the outer surface and surfaces within the tunnels. This total surface is adapted to receive catalyst composition. The catalyst support is adapted to being packed in a reactor and provides lower packed bed pressure drop.
    Type: Grant

  • Filtration method
    Patent number: 7157013
    Abstract: A method of filtering contaminants from a chemical process stream is disclosed. The method includes a step of passing the process stream over a filtration medium including a plurality of discrete filtration elements, each element having parallel first and second faces and a multi-cellular structure of substantially uniform parallel channels running from the first face to the second face. The cross-sectional shape of the channels preferably defines a polygon having angles less than or equal to 90°.
