  • Process for hydrogenation of aromatics in hydrocarbon feedstocks containing thiopheneic compounds
    Patent number: 7230148
    Abstract: The present invention relates to an improved process for the hydrogenation of aromatics in hydrocarbon feedstocks containing thiopheneic compounds as impurities, the aromatics hydrogenation being conducted in a hydrogenation reactor in the presence of a nickel based catalyst. The improvement comprises operating the hydrogenation reactor at a reaction temperature sufficiently high from the start of a run, that the thiopheneic compounds are decomposed and substantially absorbed into the bulk of the nickel catalyst, thereby substantially extending the life of the catalyst.
    Type: Grant
    Filed: April 4, 2006
    Date of Patent: June 12, 2007
    Assignee: Shell Oil Company
    Inventors: Paul Benjerman Himelfarb, Charles Eugene Wilson
