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: Methods and apparatus for separating liquid products and catalyst fines from a slurry used in a Fischer-Tropsch reactor. A settling system continuously or intermittently removes catalyst fines from the slurry and is coupled with catalyst-liquid separation system that separates liquid products from the slurry. The preferred separation system produces a sub-particle rich stream and a catalyst-lean stream that are removed from the system. The systems of the present invention act to reduce the concentration of catalyst fines in the reactor, thereby increasing the effectiveness of a catalyst-liquid separation system.

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.
