Development and evaluation of calcium oxide absorbent …

Calcium oxide based materials are attractive regenerable absorbents for separating CO{sub 2} from hot gas streams because of their high reactivity, high CO{sub 2} capacity, and low material cost. Their high carbonation temperature makes it possible to recover and use high quality heat released during CO{sub 2} capture, which increases overall process efficiency.
