The improvement of sorbent activity for extended use is imperative because sorbent replacement costs strongly influence the overall cost of CO 2 capture [].Reactivation by hydration currently appears to be a promising method for recovery of the sorbent activity [15,23,24].Another approach is thermal pretreatment of the sorbent at high temperatures [25–27].

Abstract. A fundamental study was conducted on the effectiveness of the chemical calcium magnesium acetate (CMA) as a sulfur capture agent during combustion of pulverized was based on hightemperature laboratorybench experiments with the scope of exploring the use of CMA as a "dry scrubbing" medium for inboiler injection.
ABSTRACTThe carbonate looping process is a promising technology for CO2 capture. The decay of sorbents reactivity over multiple cycles is an obstacle for realizing the carbonate looping process. In this work, the reactivity and stability of carbide slag for CO2 capture have been examined. The results show that carbide slag exhibits superior CO2 capture performance even at severe calcination ...
A simple method of CO 2 capture is by using the calcium looping cycle. The calcium looping cycle uses CaCO 3 as a CO 2 carrier, via the reversible reaction CaO(s) + CO 2 (g) = CaCO 3 (s), to extract CO2 from the exhaust stream and provide a pure stream of CO 2 suitable for sequestration.

Abstract. Through increased industry practices, land degradation, and burning of fossil fuels the anthropogenic sources of CO 2 have increased creating global concern due to the adverse impacts of climate dioxide capture and storage (CCS) technologies have been widely studied as a viable method to reduce carbon emissions.
Chemical sorbent particles are an important subset of reacting particulates. One such novel technology is the solar thermochemical capture of carbon dioxide (CO 2) via the twostep calcium oxide looping cycle [1,2]. The hightemperature capture of CO 2 via solar calcium oxide looping promises high efficiencies and capture rates [3 ...
The results are promising because they show that dolomites can be used as Calooping sorbents for CO 2 capture in power plants which flue gases CO 2 concentration is around 1015% and in the cement industry where flue gases CO 2 concentration is around 2530%. Keywords: calcium looping, carbon capture and storage, CO 2 capture, dolomite ...
Posts about Calcium oxide written by Advancements in Science. Emissions of carbon dioxide (CO 2) is considered as the main reason for global warming and ocean acidification and hence many technologies for CO 2 capture are currently emerging. Limestonederived CaO possesses a high CO 2 uptake capacity (≈ g CO 2 /g of CaO) and exhibits fast kinetics of the CO 2 capture and release.
