Abstract: The present invention relates to a method and apparatus for water removal in multi-phase reactors operating at Fischer-Tropsch conditions. In a preferred embodiment of the present invention, a method of reducing the concentration of water in a multi-phase reactor for Fisher-Tropsch synthesis containing an expanded slurry bed and a water-rich slurry region includes removing a portion of water from the water-rich slurry from a predetermined region in the reactor, removing the water from the water-rich slurry to form a water-reduced slurry, and returning the water-reduced slurry back to the reactor. Preferably the water-rich slurry region is located between nullH to H and nullR to R, where H is the height of the expanded slurry bed and R is the radius of the expanded slurry bed.

Abstract: An apparatus for converting a gaseous and/or liquid feed fluid to gaseous and/or liquid products using a solid catalyst comprises a reactor, a liquid phase disposed within the reactor volume, a fixed catalyst at least partially disposed in the liquid phase, a cooling system having a cooling element in thermal contact with the liquid phase, a feed inlet positioned to feed the feed fluid into the reactor volume, and a fluid outlet in fluid communication with the liquid phase. The catalyst is contained in a catalyst container and the container may be adjacent to said cooling element, extend through said cooling element, or may surround the catalyst container. The catalyst may be a Fischer-Tropsch catalyst.

Abstract: A gas-agitated multiphase reactor system that is effective for enabling maximum reactor productivity or minimizing reactor volume comprising at least two stages with or without recycle, wherein inlet gas superficial velocity is at least 20 cm/sec at Fischer-Tropsch synthesis, yielding a total syngas conversion of greater than about 90%, while syngas conversion in each reactor is less than 60%. More specifically, the total reactor volume is held to a minimum such that minimum reactor volume is less than 0.02 cubic meters total reactor volume/(kg C5null/hr production).

Abstract: A method for water removal in hydrocarbon product reactors operating at Fischer-Tropsch conditions. The water removal decreases the concentration of water in the reactor. In one embodiment, a method of reducing the concentration of water in a Fischer-Tropsch reactor containing a water-rich hydrocarbon product includes removing water from the water-rich hydrocarbon product of the reactor by a water removal means so as to form a water-reduced hydrocarbon product and returning that product to the reactor.

Abstract: The present invention relates to a method and apparatus for reducing the maximum water concentration in multi-phase reactors operating at Fischer-Tropsch conditions. In a preferred embodiment of the present invention, a method of reducing the maximum concentration of water in a multi-phase reactor containing an expanded slurry bed and a water-rich slurry region for Fisher-Tropsch synthesis includes changing the flow structure of a predetermined region in the reactor. The flow structure may be changed by introducing a mixing enhancing fluid into the predetermined region, installing baffles into the predetermined region, or by other methods known in the art. Preferably the predetermined region is located between null H and H and between null R and R, where H is the height of the expanded slurry bed and R is the radius of the reactor.
