  • Patent number: 5256388
    Abstract: A non-cylindrical carbon black reactor for consistently and efficiently producing high tint carbon black. A plurality of flat sides defines the inner surface of the carbon black reactor. The flat sides provide a planar surface for the introduction of feedstock hydrocarbon into the reactor, thereby eliminating or substantially reducing impingement of the feedstock hydrocarbon on the inner surface of the reactor chamber and the consequent erosion of the inner surface. The flat sides of the inner surface of the reaction chamber also provide a hot gas flow with a cross-sectional area that substantially conforms to the spray pattern of the feedstock hydrocarbon, thereby providing a minimum flame length within the reactor and a more efficient use of the hot gas.
    Type: Grant
    Filed: April 4, 1990
    Date of Patent: October 26, 1993
    Assignee: Columbian Chemicals Company
