The method comprises admixing impure calcium oxide with an aqueous solution consisting essentially of a salt of at least one compound selected from the group consisting of organic amines of the formula RNH 2 and alkanolamines of the formula NH 2 (R 1 OH), where R and R 1 are alkyl ...
The thermal performance of a chemical heat pump that uses a calcium oxide/carbon dioxide reaction system was discussed as a heat storage system for utilizing heat output from high temperature gas reactors (HTGR). Calcium oxide/carbon dioxide reactivity for the heat pump was measured using a packed...

The reactivity of calcium oxide towards carbon dioxide and its use for energy storage By using calcium carbonate powder of particle size ∼ 10 nm (and therefore of high surface area) it has been shown that the reaction CaCO3 ⇄ CaO + CO2... R Barker - 《Journal of Applied Chemistry ...
Enhanced hydrogen production from biomass with in situ carbon dioxide capture using calcium oxide sorbents The steam gasification of biomass, in the presence of a calcium oxide (CaO) sorbent for carbon dioxide ( CO 2 ) capture, is a promising pathway for the ren... NH Florin,AT Harris - ...
white, however, it can be easily colored. It is chemically stable up to 800°C and above this temperature it dissociates into calciumoxideandcarbon dioxide. It is available in both untreated and surface treated conditions; the most common surface treatments are stearic acid and calcium stearate....
