Carbon dioxide capture from combustion flue gases with a calcium oxide chemical loop. Experimental results and process development (2010, background): “However, it has also been recently established (Grasa and Abanades, 2006) that a residual activity exits (7-8% points of calcium conversion to calcium carbonate) that remains stable after many hundred of carbonation calcination cycles, and that could be able to sustain the operation of the capture p”
Ca-looping for postcombustion CO2 capture: A comparative analysis on the performances of dolomite and limestone (2015, background): “The loss of multicyclic CaO conversion is usually explained from the marked sintering 379 suffered by the CaO skeleton regenerated by calcination at high temperature [41, 43].”
