Calcination kinetics of cement raw meals under various CO
Abstract. The calcium looping CO 2 capture process, CaL, represents a promising option for the decarbonisation of cement plants, due to the intrinsic benefit of using the spent CO 2 sorbent as a feedstock for the plant. The generation of sufficiently active CaO from the raw meals entering the cement plant for the CO 2 capture requires calcination of these
