Patent ID: 8349290

Claim:
A multi-fluidized bed water-gas shift reactor including a gas reaction tank 20 which has upper and lower chambers separated by a compartment 21 placed in the middle of the tank, comprising: a high temperature catalytic reaction chamber 30 as the lower chamber partitioned in the tank by the compartment 21 , including a top reaction space 32 in which a high temperature catalyst capable of converting carbon monoxide into hydrogen at a high temperature is loaded, as well as a bottom mixing space 33 , wherein both the spaces 32 and 33 are partitioned by a porous plate 31 , a syngas input line 23 and a steam input line 24 are connected to the bottom mixing space with a preheater 25 connected to the syngas input line 23 ; a low temperature catalytic reaction chamber 40 as the top reaction chamber partitioned in the tank by the compartment wherein a low temperature catalyst is loaded in the top chamber, and a high temperature catalytic reaction gas output line 43 connected to a top of the chamber; and a cyclone 50 connected to an output line 34 which is connected to the top of the reaction chamber 30 , and the cyclone 50 is also connected to the catalytic reaction chamber 40 through a reaction gas input line 41 , and in addition the cyclone 50 is connected to a catalyst recycling line 51 .
