摘要： A method for hydroprocessing hydrocarbon products, preferably Fischer-Tropsch products, and a reactor useful for performing the method, are disclosed. The reactor includes one or more first catalyst beds comprising a catalyst useful for conducting relatively severe hydroprocessing and one or more second catalyst beds comprising a catalyst useful for conducting relatively mild hydroprocessing. The second catalyst beds are located at a position in the reactor where they can receive the products from the first catalyst bed(s), at least one of each of the first and second catalyst bed(s) comprises a catalyst grading scheme sufficient to remove at least a portion of any particulates from their respective feeds, and the reactor is set up to receive hydrocarbon feeds at a position above or within the first catalyst bed(s) and above or within the second catalyst bed(s). A first hydrocarbon feed with a relatively high boiling point is introduced to the first catalyst bed(s) and is subjected to relatively severe hydroprocessing. A feed comprising 1) the products from the hydroprocessing of the first hydrocarbon feed and 2) a second hydrocarbon feed with a relatively low boiling point is introduced to the second catalyst beds and is subjected to relatively mild hydroprocessing. The catalyst grading scheme minimizes pressure drop build-up through the catalyst beds. The hydrocarbon feeds are preferably derived, in whole or in part, from Fischer-Tropsch synthesis, although they can include products from petroleum refining or other suitable sources. In one embodiment, the relatively high boiling fraction is a predominantly C20+ fraction and the relatively low boiling fraction is a predominantly C5-20 fraction.

摘要： The present invention is directed to a method for hydroprocessing Fischer-Tropsch products. The invention in particular relates to an integrated method for producing liquid fuels from a hydrocarbon stream provided by Fischer-Tropsch synthesis. The method involves separating the Fischer-Tropsch products into a light fraction with normal boiling points below 700° F. and including predominantly C5-20 components and a heavy fraction with normal boiling points above 650° F. and including predominantly C20+ components. The heavy fraction is subjected to hydrocracking conditions, preferably through multiple catalyst beds, to reduce the chain length. The light fraction is used as all or part of a quench fluid between each catalyst bed.
