CO2 Selective Ceramic Membrane for Water-Gas-Shift Reaction With Concomitant Recovery of CO2, Quarterly Report: October - December 2001

PDF Version Also Available for Download.

Description

To become a viable CO{sub 2} transport membrane, a reversible interaction between CO{sub 2} and the membrane material at the operating condition is a must. In the past quarter, we have conducted a comprehensive reversibility study using TGA and MS at {approx}200 C for both adsorption and desorption. This quarterly report summarizes the results. Evidently, CO{sub 2} can be reversible adsorbed and desorbed on the hydrotalcite surface via a pressure swing operation (i.e., between 1 bar and vacuum). About 2wt% working capacity was obtained. Even in the presence of water, the reversibility still holds. In the next quarter, we will … continued below

In the next quarter, we will focus on the reversibility under other operating conditions and the kinetic aspect of the reversibility study.
