Calcination under low CO2 pressure enhances the Calcium Looping performance of limestone for thermochemical energy storage
(Elsevier, 2021)
The Calcium Looping performance of limestone for thermochemical energy storage has been investigated under novel favorable conditions, which involve calcination at moderate temperatures under CO2 at low pressure (0.01 and ...

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 ...

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 ...

Magnetic stabilization of fluidized beds: Effect of magnetic field orientation
(Elsevier, 2017)
Fluidized beds of granular materials can be stabilized by interparticle attractive forces which confer the expanded bed an elastic modulus that stabilizes it against flow perturbations. Stabilization in a structure of ...

Vibration-induced dynamical weakening of pyroclastic flows: Insights from rotating drum experiments
(Wiley-Blackwell, 2015)
Pyroclastic flows are characterized by their high mobility, which is often attributed to gas fluidization of the usually fine and/or low-density particles. However, the physical mechanism that might drive sustained ...

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 ...

The Calcium-Looping technology for CO2 capture: On the important roles of energy integration and sorbent behavior
(Elsevier, 2016)
The Calcium Looping (CaL) technology, based on the multicyclic carbonation/calcination of CaO in gas–solid fluidized bed reactors at high temperature, has emerged in the last years as a potentially low cost technology for ...

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 ...
