Random Pore Model

In this work, the random pore model was modified for a general concentration dependency and also bulk flow effect, in order to predict the carbonation reaction of calcium oxide with carbon dioxide. This reaction is one of the main methods for carbon dioxide capture from industrial flue gases. Different kinetic rate concentration functions were tested with the various literature experimental data for finding the best reaction constants and rate functions. Moreover, an exponential function for the diffusion of carbon dioxide through the product layer was proposed from the whole experimental conversion-time profiles.
