A Novel Method of CO 2 Capture from High Temperature Gases

Abstract

Lithium zirconate powder reacts immediately with ambient in the range of 450 to 550°C. Moreover the products react and return reversibly to lithium zirconate at temperatures above 650°C. Utilizing this reaction, the possibility of a separation system which operates at around 550°C is suggested. A separation process operable at temperatures beyond 500°C may have a special benefit, because the separation can be achieved directly during the fuel reforming process, where high concentration is expected.
