Gas-liquid-solid three-phase slurry bed industrial reactor capable of achieving continuous operation

Abstract

A gas-liquid-solid three-phase slurry bed industrial reactor capable of achieving continuous operation comprises an inlet gas distribution component composed of a false bottom and inlet gas distribution tubes, one or more layers of heat exchange tube components used for heating/cooling the bed, one or more layers of liquid-solid separator components capable of being cleaned automatically, an outlet gas-liquid-solid entrainment separation component located in the upper portion of the interior of the reactor and used for removing liquid foam and solid entrainments, a plurality of layers of solid concentration uniform distribution devices used for reducing the catalyst concentration gradient and the inlet-outlet temperature difference of the reactor, a flow guiding device located on a component support beam and used for preventing catalyst accumulation, and auxiliary systems including a filter-backflush system and a washing system. Compared with the prior art, the reactor is low in energy consumption and solves the problems of blockage, backflow and dead zones, the temperature and liquid level are well controlled, catalysts can be easily added and discharged online, and stable and continuous operation of the reactor is achieved. The reactor is suitable for being applied to the Fischer-Tropsch synthesis process on an industrial scale.
