Abstract: A system for producing a hydrocarbon by high-temperature Fischer-Tropsch synthesis is described. The system includes a Fischer-Tropsch synthesis unit, a reaction water separation unit, and a catalyst reduction unit. The catalyst reduction unit uses a gas containing the tail gas of the synthesis unit as a reducing gas and a small amount of synthesis gas for adjusting the hydrogen to carbon ratio, to react with the Fischer-Tropsch synthesis catalyst. After the reduction reaction, the reacted gas is cooled to room temperature, and enters a gas-liquid separator to obtain a gas phase and a liquid phase. The gas phase flows to a cryogenic separation unit to recover gaseous hydrocarbons. The liquid phase is separated into reaction water and Fischer-Tropsch oil products. The reduced catalyst is sent to the Fischer-Tropsch synthesis unit.

Abstract: An equal flow scale catcher device, or EFSC, is designed based on a unique scale catching technology for a reactor. With multiple scale catching modules, the EFSC offers equal flows to a catalyst bed or distribution tray of the reactor, independent of each module's degree of saturation with particles of an incoming fluid during operation. Thus, the innovative EFSC system achieves substantial uniformity of fluid delivery across the distribution tray of the reactor and the static pressure field above the liquid level on the distribution tray. Further, the EFSC effectively captures solid particles in the incoming fluid to the reactor and solid particles that form at the top head of the reactor. The EFSC employs a modular structure that allows optimal configuration of the scale catching modules and scale catching units inside each scale catching module, thus efficiently facilitating simple and efficient installation, maintenance, and/or replacement of the EFSC.
