Abstract:
The Pd-based water-gas shift membrane reactor (WGS-MR) is a promising technology for pre-combustion CO2 capture and hydrogen production. A conceptual study on a tubular WGS-MR performance with an inner permeation diffuser flow for the syngas is investigated by numerical simulation. The results reveal that both the CO conversion and H2 recovery of membrane reactors are improved. From a physical point of view, the time both for WGS reaction and for H2 permeation through membrane becomes longer as the syngas goes through the channel of diffuser flows. This fact implies that the performance of WGS-MR will be enhanced if the diffuser flow channel is adopted.
