CO2 SELECTIVE CERAMIC MEMBRANE FOR WATER-GAS SHIFT REACTION WITH CONCOMITANT RECOVERY OF CO2
This quarterly report focuses on the two specific topics: (1) Reversibility of CO{sub 2} affinity of hydrotalcite materials; and (2)In-situ crystallization of hydrotalcite on commercial tubular ceramic membrane as substrate. The former relates to the foundation of the use of the hydrotalcite material as a membrane. The later addresses the first step of the membrane synthesis we propose. Our study concludes that the CO{sub 2} affinity of the hydrotalcite material is reversible at 150 C and in the presence of water using TG/MS. Additional study at a high pressure and/or high temperature will be performed to scope the operating range of the membrane. On the other hand, the in-situ crystallization is proven to be an effective first step for the hydrotalcite membrane synthesis. Our result indicates that about hydrotalcite covers about 50% of the porosity of the substrate, ideal as a seed for the 2nd step involving in-situ crystal growth. Our next quarterly report will report the result from the study on the 2nd step.
