We report the use of gas sorption experiments and in situ powder X-ray diffraction to study the use of dolomite (MgCa(CO 3) 2) as a potential reversible high-temperature CO 2 sorbent. When dolomite is treated in inert atmosphere at 900 °C it decomposes into separate CaO and MgO rich phases and dolomite is never reformed upon CO 2 sorption. Gas sorption studies show that the calcined …
