The causes of catalyst deactivation can be ascribed to three main factors: (i) mechanical, (attrition/entrainment), (ii) thermal, (sintering), and (iii) chemical, (poisoning, coking, phase changes. The dynamics of catalyst activation-deactivation caused by ions diffusion in active component has been studied. Besides, the influence of reagent capillary condensation upon catalytic reactions.   The literature treating mechanisms of catalyst deactivation is reviewed. Intrinsic mechanisms of catalyst deactivation are many; nevertheless, they can be classified into six distinct types: (i) poisoning, (ii) fouling, (iii) thermal degradation, (iv) vapor compound formation accompanied by transport, (v) vapor-solid and/or solid-solid reactions, and (vi) attrition/crushing. Catalyst Deactivation. Catalyst deactivation can be prevented by performing the process in two steps: the first step is pyrolysis, and the second step is a catalyst reforming reaction in which gases from the pyrolysis product are treated at higher temperatures for selectivity [44].

This proceedings contains the papers presented at the 9th International Symposium on Catalyst Deactivation, held in Lexi Brand: Elsevier Science. The catalyst deactivation of MTO reaction over zeolite and SAPO catalysts is closely related to the catalyst acidity. The catalysts with stronger acid strength and higher acid site density are generally subject to quick deactivation (,,).Guisnet and coworkers () summarized the role played by the acidity and pointed out that (i) the catalyst with stronger acid strength would cause. An overview of deactivation mechanisms, their causes and consequences, as well as of methods and techniques of investigation of deactivation is presented. There are three fundamental reasons for catalyst deactivation, i.e. poisoning, coking or fouling and ageing. Poisoning can be reversible or irreversible, and with geometric or electronic effect.
