摘要: 充分考虑水和积炭对反应的影响,建立SAPO-34催化剂上的甲醇制烯烃反应动力学模型。考虑甲醇制烯烃反应过程的三个步骤,将产物划分为5个组分的集总。进料中加入适量的水,不仅可以降低甲醇的浓度,而且可以减缓SAPO-34催化剂的失活。通过最小二乘法对模型的动力学参数进行估计。结果表明:模型的计算值与实验值吻合良好。

Abstract: 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.
