✦ Synopsis

A general equation is derived that predicts the evolution of pore volume distribution during isothermal gasification in the regime of kinetic control, starting from a given initial condition. The development takes into account pore enlargement as well as pore intersections. Equations are also derived for the special cases of (1)uniform pore size and (2) bimodal distribution. The results are used to interpret the experimental data of Tomkow et al. (1977) and Kawahata and Walker (1962).
