Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The pore structure evolution and reaction characteristics of limestone with different particle sizes during thermal decomposition were investigated experimentally. A kinetic model considering the effect of pore structure evolution was developed to simulate the multiscale coupling of the mesoscale pore structure with the macroscopic transport and microscopic chemical reaction. Over a defined particle size range, the calculated results were in good agreement with the experimental data including the influence of gas diffusion throughout the whole decomposition course. A dimensionless Thiele modulus <italic>Th</italic> was constructed for assessing the critical point corresponding to the transformation of controlled mechanisms.</p> </abstract>
