Preparation of Cerium-Hierarchical SAPO-34 Catalyst and Presentation of a Kinetic Model for Methanol to Propylene Process (MTP)

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.
