“…Soong et al [121] proposed the use of coal combustion fly ash and brine solutions (waste from oil and gas production) to sequester CO 2 via a multi-step aqueous mineral carbonation process. For the study, Ca-rich fly ash (29 % CaO) was added at 18°C to increase the pH-level of the reactant brine (also containing Ca) from a pH of about 3.0 to above 9.0.…”

Research on carbon capture and storage has been focused on CO 2 storage in geologic formations, with many potential risks. An alternative to conventional geologic storage is carbon mineralization, where CO 2 is reacted with metal cations to form carbonate minerals. Mineralization methods can be broadly divided into two categories: in situ and ex situ. In situ mineralization, or mineral trapping, is a component of underground geologic sequestration, in which a portion of the injected CO 2 reacts with alkaline rock present in the target formation to form solid carbonate species. In ex situ mineralization, the carbonation reaction occurs above ground, within a separate reactor or industrial process. This literature review is meant to provide an update on the current status of research on CO 2 mineralization.

“…Therefore, more extensive information on the leaching and carbonation performance of FA is essential for developing the technology as well as FA disposal. In the literature, many studies have investigated the leaching efficiency using acidic solvents such as brine, saline, waste acid and acidic rain [22][23][24], and have measured the carbonation capacity under highly pressurized condition with already captured CO 2 to increase the carbonation capacity. However, a large amount of energy is consumed to maintain the high pressure during the carbonation [25][26][27].…”

“…Complementary CO 2 retention technologies, such as mineral sequestration via reaction of CO 2 with Mg-Ca-silicate rocks and/or neoformation of carbonate minerals in aqueous solutions, are attractive for their permanent and safe CO 2 storage in a solid form (Soong et al, 2006). The methods based on neoformation of carbonates or bicarbonates, requires cations to neutralize CO 2 (Lackner et al, 1995;O'Connor et al, 2002).…”
