Role of precalcination and regeneration conditions on postcombustion CO2 capture in the Ca-looping technology
(Elsevier, 2014)
The Ca-looping (CaL) technology is already recognized as a potentially viable method to capture CO2 from postcombustion gas in coal fired power plants. In this process, CO2 is chemisorbed by CaO solid particles derived ...

Large-Scale Storage of Concentrated Solar Power from Industrial Waste
(American Chemical Society, 2017)
Deep penetration of renewable energies into the grid relies on the development of large-scale energy storage technologies using cheap, abundant, and nontoxic materials. Concentrated solar power (CSP) is particularly suitable ...

Synthesis of a nanosilica supported CO2 sorbent in a fluidized bed reactor
(Elsevier, 2015)
CaO has been deposited on a nanosilica powder matrix by a procedure based on atomic layer deposition (ALD) in a fluidized bed reactor at atmospheric pressure following a potentially scalable process. In previous works ALD ...

Use of steel slag for CO2 capture under realistic calcium-looping conditions
(Royal Society of Chemistry, 2016)
In this study, CaO derived from steel slag pretreated with diluted acetic acid has been tested as a dry sorbent for CO capture under realistic Ca-Looping (CaL) conditions, which necessarily implies calcination under high ...

Nanosilica supported CaO: A regenerable and mechanically hard CO2 sorbent at Ca-looping conditions
(Elsevier, 2014)
This work presents a CO2 sorbent that may be synthesized from low-cost and widely available materials following a simple method basically consisting of impregnation of a nanostructured silica support with a saturated ...

Role of looping-calcination conditions on self-reactivation of thermally pretreated CO2 sorbents based on CaO
(American Chemical Society, 2013)
The conversion of thermally pretreated CaO along successive carbonation/calcination cycles has been investigated, as affected by looping-calcination conditions, by means of Thermogravimetric Analysis (TGA). Sorbent samples ...

Thermal decomposition of dolomite under CO2: insights from TGA and in situ XRD analysis
(Royal Society of Chemistry, 2015)
Thermal decomposition of dolomite in the presence of CO2 in a calcination environment is investigated by means of in situ X-ray diffraction (XRD) and thermogravimetric analysis (TGA). The in situ XRD results suggest that ...

On the relevant role of solids residence time on their CO2 capture performance in the Calcium Looping technology
(Pergamon Press, 2016)
The multicycle CO capture performance of CaO derived from natural limestone and dolomite has been investigated by means of thermogravimetry under realistic Calcium-Looping conditions, which necessarily involve high CO ...
