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 ...

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 ...

Alternating Field Electronanofluidization
(American Institute of Physics, 2009)
The use of fluidized beds to remove submicron particles from gases has been investigated since 1949. High efficiency removal was achieved in the 1970’s by imposing an electric field on a fluidized bed of semi-insulating ...

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 ...

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 ...

Mesoscopic structuring and yield stress of magnetofluidized fine particles
(IOP Publishing Ltd., 2009-10)
The fluidization behavior of a bed of fine magnetizable particles excited by an externally applied magnetic field is found to depend on the aggregative nature of the particles before the field was applied. Usually nonaggregated ...

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 ...
