It introduces mathematical tools that can be used to calculate the effectiveness of catalyst pellets as a function of shape, size, pore size, type of kinetics and diffusion, as well as temperature and pressure conditions -- a method applicable to laboratory as well as large-scale operations. The practical value of the text is enhanced by some 30 examples of optimizing catalysts and troubleshooting."]
