CO2 SELECTIVE CERAMIC MEMBRANE FOR WATER-GAS SHIFT REACTION WITH CONCOMITANT RECOVERY OF CO2

PDF Version Also Available for Download.

Description

During Year I this project has been focused on these two topic areas: (i) understanding comprehensively the CO{sub 2} affinity vs temperature, reversibility of CO{sub 2} affinity, and the role of water in order to select an optimum hydrotalcite composition for membrane preparation, and (ii) developing a membrane synthesis protocol for depositing the hydrotalcite material into a commercially available ceramic membrane from us. This annual report documents the progress we have made in these areas. In summary, the Year I study has demonstrated the technical feasibility of preparing a hydrotalcite. The proposed membrane synthesis protocol will be refined and optimized ... continued below

Description

During Year I this project has been focused on these two topic areas: (i) understanding comprehensively the CO{sub 2} affinity vs temperature, reversibility of CO{sub 2} affinity, and the role of water in order to select an optimum hydrotalcite composition for membrane preparation, and (ii) developing a membrane synthesis protocol for depositing the hydrotalcite material into a commercially available ceramic membrane from us. This annual report documents the progress we have made in these areas. In summary, the Year I study has demonstrated the technical feasibility of preparing a hydrotalcite. The proposed membrane synthesis protocol will be refined and optimized in Year II. In addition, surface analysis techniques employing FTIR and DRIFTS have been developed. These techniques have been applied to a hydrotalcite model compound to demonstrate our ability to screen hydrotalcite materials in terms of its composition and % of cation substitution. These techniques will be utilized in Year II to formulate an optimized hydrotalcite candidate for preparing a membrane with maximized CO{sub 2} transport at the proposed process condition.
