The invention discloses a fluidized bed reactor. The fluidized bed reactor comprises a reactor shell and a circulating unit, wherein the circulating unit is arranged outside the reactor shell; a material outlet which is connected to the circulating unit is formed in the top of the reactor shell; a material inlet which is communicated with the circulating unit is formed in the bottom of the reactor shell; the circulating unit comprises a separator and a circulating pump; the separator is used for separating reaction materials from the top of the reactor shell into gas-phase materials and liquid-phase materials; the circulating pump is used for feeding part of the liquid-phase materials separated by the separator into the reactor shell. The effective volume of the fluidized bed reactor is increased, and the flexibility and stability of operation are improved; meanwhile, by the arrangement of a separation device in the circulating unit, the content of solid particles in the fed materials of the circulating pump is decreased, and abrasion of the circulating pump is reduced, so that the service life of the circulating pump is prolonged.
Description
Technical field [0001] The invention relates to a fluidized bed reactor, in particular to a fluidized bed reactor capable of allowing materials to undergo extracorporeal circulation. Background technique [0002] The fluidized bed reactor is a reactor that uses gas or liquid to pass through the granular solid catalyst bed to make the catalyst in a suspended motion state, and carry out the gas, liquid, and solid three-phase reaction. The fluidized bed reactor can process heavy and inferior feedstock oils with high metal content and high asphaltene content. It has the advantages of large space velocity, small bed pressure drop, uniform temperature distribution, good mass and heat transfer effects, and flexible device operation. In addition, fresh catalyst can be added online and deactivated catalyst can be unloaded during operation, so that the activity of the catalyst is maintained at a higher level during the entire operation cycle, and the operation period is longer.
