Effects of Steam Addition on the Properties of High Temperature Ceramic Acceptors
Publication: Journal of Environmental Engineering
Volume 135, Issue 6
Abstract
The effects of steam addition on the stability and capture and regeneration properties of , K-doped , , and at relevant sorption enhanced steam methane reforming conditions has been investigated. It has been observed that the presence of water in the form of steam enhances the capture and regeneration rates. However, a large decay in the capacity is observed when compared to the performance of the acceptors in dry conditions. The reasons for the improved kinetics are not clear, but a higher mobility of the alkaline ions is suggested. The losses in capacity could be due to sintering under high pressure of steam, vaporization of alkali metals, and/or phase segregation.
