Effect of heat pretreatment/recarbonation in the Ca-looping process at realistic calcination conditions
(American Chemical Society, 2014)
Even though an increasing number of pilot-scale plants are demonstrating the potential efficiency of the Ca-looping technology to capture CO2 at a commercial level, a still standing matter of concern is the loss of carbonation ...

Steam-enhanced calcium-looping performance of limestone for thermochemical energy storage: The role of particle size
(Elsevier, 2022)
Steam injection has been proposed to attenuate the decay of CaO reactivity during calcium looping (CaL) under operating conditions compatible with carbon capture and storage. However, it is yet unknown whether the perceived ...

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 ...

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 ...

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 ...

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 ...
