摘要：
The effect of water concentration on the reaction medium in order to attenuate coke formation on a SAPO-34 has been studied in the transformation of methanol into olefins. From the results obtained in an integral reactor for different values of space time and water concentration in the feed, a kinetic model for deactivation by coking on a SAPO-34 in the 623-748 K range has been proposed. The model takes into account the effect on the deactivation of organic components and water in the reaction medium.
