Abstract
In this review article, we are mainly focused on discussion and analysis of techniques reported in patents and studies in the field of CO2 capture and sequestration from atmospheric air and flue gases with the use of pure Ca(OH)2 dispersions and Ca(OH)2-comprising sorbents. The discussed CO2 capture techniques are classified in terms of the composition of Ca(OH)2-comprising sorbents. The physicochemical aspects of the carbonation process of Ca(OH)2 dispersions are discussed and analyzed as well.
Keywords: Calcium hydroxide, carbonation mechanism, carbonation reaction, CO2 capture, hydrogen co-production, patents.
