Abstract:
1. A fluidized bed water gas shift membrane reactor for simultaneously separating carbon dioxide, by reacting carbon monoxide in a synthetic gas with steam in the presence of a fluidized catalyst to produce hydrogen and carbon dioxide, and separating the hydrogen to concentrate the carbon dioxide, the reactor comprising: a reaction chamber partitioned into a lower-layer inlet portion, an intermediate-layer reaction portion and an upper-layer separation portion through a diffuser and a shift membrane, the reaction chamber provided with a catalyst layer arranged on the diffuser catalyst to allow fluidization to be realized using a fluidization gas supplied from the lower-layer inlet portion; a synthetic gas supply pipe and a steam supply pipe communicating with the lower-layer inlet portion, to supply synthetic gas and steam as catalyst fluidization gases; a hydrogen exhaust pipe communicating with the top of the upper-layer separation portion to discharge hydrogen separated by the shift membrane; and a mix gas outlet pipe communicating with the top of the intermediate-layer reaction portion to discharge hydrogen-free high-concentrate carbon dioxide.
