  • Method of manufacturing a reducing gas useful in a direct reduction process
    Patent number: 4156659
    Abstract: A method of reforming a fluid to make it suitable for use as a reducing gas in a direct reduction process is provided. The method is also taught in conjunction with a specific process for which it is particularly suited. The method uses a high-temperature gas-cooled nuclear reactor as a heat source for a catalytic reformer which is coupled with a cryogenic gas separation step to remove a substantial amount of the unreacted hydrocarbon.
    Type: Grant
    Filed: May 4, 1977
    Date of Patent: May 29, 1979
    Assignee: United States Steel Corporation
    Inventor: Thomas F. Barnhart
