  • Method for activating an iron-based fischer-tropsch catalyst
    Patent number: 7683006
    Abstract: A method for transforming at least a part of the catalyst precursor hematite into x-carbide (Fe5C2) and ??-carbide (FeC2.2) without a large amount of fines generation. This method slows the transformation of the hematite to iron carbides by reducing the partial pressure of the synthesis gas by inert gas dilution. The activation time is about three to about five hours.
    Type: Grant
    Filed: March 27, 2009
    Date of Patent: March 23, 2010
    Assignee: Rentech, Inc.
    Inventors: Dennis L. Yakobson, Elijah C. Philipp, Mark S. Bohn

  • Method for activating an iron-based fischer-tropsch catalyst
    Patent number: 7544719
    Abstract: A method for transforming at least a part of the catalyst precursor hematite into ?-carbide (Fe5C2) and ??-carbide (FeC2.2) without a large amount of fines generation. This method slows the transformation of the hematite to iron carbides by reducing the partial pressure of the synthesis gas by inert gas dilution. The activation time is about three to about five hours.
