High solids flux circulating carbonation reactor

摘要

The present invention relates to a method for capturing carbon dioxide CO 2 by carbonation in a circulating fluidized bed (CFB) carbonation reactor (10) wherein temperature profile is adjusted by recirculation of solid fractions of metal oxide MeO and metal carbonate MeCO 3 to the CFB carbonation reactor (10). Also a system (1) recirculating the metal oxide MeO and metal carbonate MeCO 3 is provided by the invention.
