This paper reports on the effect of heating rates between 0.1 ◦C/s and 205.0 ◦C/s on the thermodynamics and kinetics of limestone calcination in air. These heating rates are orders of magnitude higher than those used in the thermogravimetric analysers that have been reported previously (0.1 ◦C/s to 0.8 ◦C/s). It was found that the activation energy, E, is reduced by 59%, from 205.0 kJmol− 1 to 84.5 kJmol − 1 , when the heating rate is increased from a low heating rate regime (
