  • Hydrodesulfurization apparatus with upstaged reactor zones
    Patent number: 4045182
    Abstract: A process and apparatus for the hydrodesulfurization of residual oil in a plurality of catalyst zones in series with the upstream reactor being removed periodically for a catalyst change. When an upstream zone is taken off-stream for a catalyst change, the fresh feed oil is passed to a succeeding downstream zone so that the downstream catalyst zone is upstaged to the status of an upstream catalyst zone. When a zone is returned to service after a catalyst change, it enters the process as a downstream reactor in the series.
    Type: Grant
    Filed: August 17, 1976
    Date of Patent: August 30, 1977
    Assignee: Gulf Research & Development Company
