✦ Synopsis

The effectiveness of a catalyst particle with diffusion and first-order reaction is governed by a parameter proportional to the 'size' of the particle. If that size is taken to be the ratio of the volume to external surface area, the effectiveness factors for all particle shapes come together asymptotically and are reasonably close together over the whole range.

The problem of heat or matter transfer for a bed of spherical particles has been fully solved by AMIJNDSON. In this paper we consider the modifications which must be made in steady state solution when the bed may consist of irregularly shaped particles. Considering the case of diffusion limitation o
