ABSTRACT:
A continuous process is disclosed for the production of hydrocarbon liquids and wax by Fischer-Tropsch conversion of synthesis gas in contact with promoted skeletal iron catalyst particles in a slurry reactor. Wax product is readily separated from the skeletal iron catalyst in a catalyst settling drum and concentrated catalyst particles in wax slurry are recycled from the settling drum to the slurry reactor, while essentially solid-free wax is recovered as a product.
