Regeneration of sintered limestone sorbents for the sequestration of CO2 from combustion and other systems. Fennell, P.S.; Davidson, J.F.; Dennis, J.S.; Hayhurst, A.N. Journal of the Energy Institute, Volume 80, Number 2, June 2007 , pp. 116-119
The capacity of particles of CaO, produced by calcining limestone, to reactively absorb CO2, degrades with the number of cycles of carbonation and calcination. A novel method of reactivating the stone in humid, ambient air is described. Typically, a calcined limestone has a carrying capacity for CO2 which falls from ~79% (on the basis of moles of CO2 per mole of CaO) to only about 20-30% after 30 cycles of regeneration and reuse. This new technique enables the carrying capacity to be restored to ~55%, thereby improving the economics of sequestrating CO2 using a calcium-based sorbent.
