Calcium looping - Wikipedia

Calcium looping (CaL), or the regenerative calcium cycle (RCC), is a second-generation carbon capture technology. It is the most developed form of carbonate looping, where a metal (M) is reversibly reacted between its carbonate form (MCO 3) and its oxide form (MO) to separate carbon dioxide from other gases coming from either power generation or an industrial plant.

Introduction The Calcium Looping Cycle is an emerging CO2 capture process which uses natural limestone cycled in a twin circulating fluidised bed (CFB) reactor system. The process has been reviewed elsewhere [1, 2] along with estimates for economic costing and efficiency penalty of different potential configurations [3]. The process offers several important benefits over competing CO2 capture ...

Calcium Looping for Carbon Dioxide and Sulfur Dioxide Co ...

It was discovered that metamorphosed limestone-derived sorbents exhibit atypical capture behavior: flue gas H2O negatively influences CO2 capture performance, while limited sulfation can positively influence CO2 capture. The morphological characteristics influencing sorbent capture behavior were examined using imaging and material characterization tools, and a detailed discussion is presented.
