✦ Synopsis
transient analysis of the foulmg of porous catalyst particles has been made usmg two models, m one of wluch an Isothermal pellet IS assumed while m the other Wraparticle gradients of both temperature and concentratron are consldered To account for the relative rate of foulmg compared with the mam reaction and hence to determme whether transient or pseudo-steady analysts IS appropnate a new parameter termed the charactenshc parameter for fouling IS employed The effect of this parameter and Lewis number are consldered and a comparison IS made with pseudo-steady state analyses Fmally, a comparison IS made of catalyst multiple steady states under fouhng condlhons usmg both types of analysis

This paper develops the effectiveness factors of catalysts for two reaction models and shows that this factor is dependent not only upon size, shape, effective diffusivity and surface reaction velocity constant, but also upon the reaction model, surface coverage by adsorption, degree of conversion a
