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 ...

Kinetic analysis of complex solid-state reactions. A new deconvolution procedure
(American Chemical Society, 2011)
The kinetic analysis of complex solid-state reactions that involve simultaneous overlapping processes is challenging. A method that involves the deconvolution of the individual processes from the overall differential kinetic ...

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 ...

Kinetics and cyclability of limestone (CaCO3) in presence of steam during calcination in the CaL scheme for thermochemical energy storage
(Elsevier, 2021)
In the present work, we explore the use of steam in the CaCO3 calcination step of a calcium looping process devised for integration into a thermochemical energy storage process (CaL-TCES). Steam produces a double benefit: ...

A new model for the kinetic analysis of thermal degradation of polymers driven by random scission
(Elsevier, 2010)
In this paper, a series of f(α) kinetic equations able to describe the random scission degradation of polymers is formulated in such a way that the reaction rate of the thermal degradation of polymers that go through a ...
