ملخص المقالة :

In this paper, a new lumped kinetic model for methanol to propylene process (MTP) over CeriumHierarchical SAPO-34 catalyst was developed based on data obtained from a micro catalytic reactor in the temperature range of 390–450°C and at atmospheric pressure, using appropriate reaction network. The Ce-HSAPO-34 zeolite was synthesized by hydrothermal method in the presence of nporopylamine as a mesoscale template and pore size modifier. The reaction rate equation has been introduced with consideration of reaction mechanism and the parameters were optimized on the experimental data by genetic algorithm. Comparing the experimental and predicted data showed that the predicted values from the presented model are well fitted to the experimental data.
