Ca-looping for postcombustion CO2 capture: A comparative analysis on the performances of dolomite and limestone
(Pergamon Press, 2015)
The low cost and wide availability of natural limestone (CaCO3) is at the basis of the industrial competitiveness of the Ca-looping (CaL) technology for postcombustion CO2 capture as already demonstrated by ~1Mwt scale ...

Phase-pure BiFeO3 produced by reaction flash-sintering of Bi2O3 and Fe2O3
(Royal Society of Chemistry, 2018)
Mixed powders of Bi2O3 and Fe2O3 are shown to yield single-phase, dense nanostructured polycrystals of BiFeO3 in reaction flash sintering experiments, carried out by applying a field of 50 V cm 1 and with the current ...

Magnesium hydride for energy storage applications: The kinetics of dehydrogenation under different working conditions
(Elsevier, 2016)
A new approach to the kinetics of magnesium hydride dehydrogenation is considered. A model able to predict the dehydrogenation under different experimental conditions has been proposed. A new combined kinetic analysis ...

Scission kinetic model for the prediction of polymer pyrolysis curves from chain structure
(Elsevier, 2014)
There is a significant interest in correlating polymer structure with thermal degradation behavior. Thus, polymer pyrolysis curves could be predicted from the chemical structure of the polymer. Recent proposals correlate ...

Influence of ball milling on CaO crystal growth during limestone and dolomite calcination: Effect on CO2 capture at Calcium Looping conditions
(American Chemical Society, 2016)
The multicycle CO2 capture performance of CaO derived from the calcination of ball-milled limestone and dolomite have been tested under high temperature and high CO2 concentration environment for the first time. Here it ...

Relevant influence of limestone crystallinity on CO2 capture in the Ca-looping technology at realistic calcination conditions
(American Chemical Society, 2014)
We analyze the role of limestone crystallinity on its CO2 capture performance when subjected to carbonation/calcination cycles at conditions mimicking the Ca-looping (CaL) technology for postcombustion CO 2 capture. The ...

Limestone calcination nearby equilibrium: Kinetics, CaO crystal structure, sintering and reactivity
(American Chemical Society, 2015)
In this work, we analyze limestone calcination kinetics at environmental conditions involving a CO2 partial pressure P close to the equilibrium pressure Peq by means of in situ X-ray diffraction (XRD) and thermogravimetric ...

Characterization of thermally stable gamma alumina fibres biomimicking sisal
(Elsevier, 2014)
Mesoporous gamma alumina fibres of high surface area, stable up to 1000°C, were synthesized by bioreplica technique using sisal fibres as templates. Alumina formation during pyrolysis and calcination of fibres infiltrated ...

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 ...
