In recent years, there have been increasing interests in membrane reactors for producing H2 with simultaneous CO2-capture through single-step water gas shift (WGS) of fossil- and biomass-derived syngas. In this study, MFI zeolite membranes supported on porous α-alumina tubes have been modified by means of catalytic cracking deposition (CCD). The modified MFI-type zeolite membranes achieved high H2 permselectivities over CO2 and CO (>50) with high H2 permeance (>1.5×10-7 mol.s-1.m-2.Pa-1) and good hydrothermal stability. WGS reaction has been tested in the zeolite membrane reactor (MR) packed with metal-doped nano-crystalline ferrite catalysts in a temperature range of 350-500oC under pressures up to 5 bars.
