文摘A kinetic model of MTO process over the SAPO-34 catalyst considering the effect of water and coke deposition has been proposed.The model takes into account three steps of the MTO reaction in which the products cover 5 lumped components.The water in the feed not only reduces the concentration of methanol but also alleviates the deactivation of SAPO-34 catalyst.The kinetic parameters have been estimated by the least square method.It has been proved that the calculated values in the kinetic model are in good agreement with the experimental values.
