Effect of catalyst fouling in fixed-, moving-, and fluid-bed reactors

Abstract

A quantitative means of assessing the performance of fixed-, moving-, and fluid-bed reactors under conditions of catalyst fouling is presented. The treatment covers simple reactions of general order in which the effect of different decay forms is considered, the role of axial diffusion is examined, and an expression is developed for the effect of catalyst decay on yield in a consecutive reaction. Finally the practical implications of the development are considered through an example.
