✦ Synopsis
The effectiveness factor for the isothermal power-law decomposition of a reactant within symmetrical catalytic pellets is obtaned from the solution of a single first order differential equation The effects of external mass transfer are taken into account, as well as the effect of simple types of non-uniform distribution of the catalyst within the particle
For fractional and negative reaction orders there are solutions with zero concentration in a central region of the particle For negative reaction orders intervals of multiplicity of solutions are found

This paper considers the combined effect of longitudinal diffusion and external mass transfer resistance on the performance of fixed bed processes with a favourable non-linear isotherm. It is shown that., whereas the linear additive principle is obeyed when the isotherms are " almost linear," for no
