Notes:
A general expression for the time-dependence of the activity of a catalyst pellet affected by both chemical deactivation and diffusion is developed. Specific results are given for both uniform and pore-mouth poisoning, with parallel and series poisoning mechanisms. Comparisons show a satisfactory agreement between theoretical and experimental results. A pellet effectiveness representing the combined effect of deactivation and diffusion is also developed in a form suitable for direct inclusion in reactor conservation equations.
