New insights on the kinetic analysis of isothermal data: The independence of the activation energy from the assumed kinetic model
(American Chemical Society, 2015)
Isothermal experiments are widely employed to study the kinetics of solid-state reactions or processes to extract essential kinetic information needed for modeling the processes at an industrial scale. The kinetic analysis ...

Effect of dolomite decomposition under CO2 on its multicycle CO2 capture behaviour under calcium looping conditions
(Royal Society of Chemistry, 2016)
One of the major drawbacks that hinder the industrial competitiveness of the calcium looping (CaL) process for CO capture is the high temperature (∼930-950 °C) needed in practice to attain full calcination of limestone in ...
