  • Methods for pre-conditioning fischer-tropsch light products preceding upgrading
    Patent number: 6709569
    Abstract: Embodiments of the present invention are directed to methods for hydroprocessing Fischer-Tropsch products. The embodiments in particular are related to integrated methods for producing liquid fuels from a hydrocarbon stream provided by a Fischer-Tropsch synthesis process. The methods involves separating the Fischer-Tropsch products into a light fraction and a heavy fraction. The light fraction is pre-conditioned to remove contaminants such as CO2 prior to being subjected to hydroprocessing, either separately, or after having been being recombined with the heavy fraction. Any of the hydroprocessing steps may be accomplished in a single reactor.
    Type: Grant

    Date of Patent: March 23, 2004
    Assignee: Chevron U.S.A. Inc.
    Inventors: Richard O. Moore, Jr., Paul D. Cambern
  • Process for preparation of fuels and lubes in a single integrated hydrocracking system
    Patent number: 6623624
    Abstract: An integrated distillate hydrocracking process produces one or more fuel products and one or more lube products from a first reaction stage. Heavy fractions from the first stage, which are not recovered as lube products, are cracked to fuels in a second reaction stage. This invention is intended to provide a full range of lube streams, over a wide viscosity range and a wide viscosity index range, from a fuels hydrocracker, in addition to high yields of high quality fuels.
