Abstract: A solid sorbent composition including as chemical components: calcium oxide, calcium aluminate, and a mixed metal oxide characterized by a perovskite crystalline structure. The solid sorbent finds utility in capturing carbon dioxide from any gaseous stream containing carbon dioxide, such as emissions streams produced in combustion processes or streams derived from closed environments including airplanes, spaceships, and submarines. A reversible carbon dioxide looping process is disclosed involving (a) contacting a carbon dioxide-containing gaseous stream with the solid sorbent composition in a carbonator to produce a solid mixture containing calcium carbonate and a gaseous stream reduced in carbon dioxide concentration; and (b) heating the solid mixture containing calcium carbonate in a calcinator (decarbonator) to regenerate the solid sorbent composition and to produce a gaseous stream enriched in carbon dioxide.
