摘要
An integrated process for producing liquid fuel and lubricating base oil from Fischer-Tropsch derived products which comprises (a) recovering separately from a Fischer-Tropsch synthesis reactor a Fischer-Tropsch wax and condensate; (b) hydroprocessing the wax and recovering a waxy intermediate and a hydrogen-rich normally, liquid fraction; (c) mixing the condensate and at least part of the hydrogen-rich normally liquid fraction to form a Fischer-Tropsch condensate mixture; (d) hydrotreating the condensate mixture and recovering a Fischer-Tropsch condensate product; (e) recovering from the condensate product a liquid fuel; (f) separately dewaxing the waxy intermediate and recovering a base oil; (g) hydrofinishing the base oil; (h) recovering from the hydrofinishing zone a stabilized base oil and a hydrogen-rich gas; and (i) recycling the hydrogen-rich gas to the wax hydroprocessing zone wherein the total pressure in the hydrofinishing zone is at least as high as the total pressure in the wax hydroprocessing zone.
