methanol to propylene (mtp) process modeling and calculation of effectiveness parameters

In this work, based on the kinetics obtained in previous work and the experimental data of a fixed bed reactor and by providing a one-dimensional model for the reactor and optimizing by genetic algorithm, the effectiveness factors for the zsm-5 catalyst were obtained at 420-450 ° c# it was observed that the temperature changes at this range had negligible effect on the effectiveness parameters# by using the obtained factors at 480 and 500 ° c and comparing the result of model and experiments data at these temperatures, these factors were confirmed# in the next step, the mathematic modeling of the methanol to propylene fixed bed reactors has performed in two level; one-dimensional and two-dimensional# the results of model were compared with the experiment result of the mtp pilot plant in npc-rt company# the comparison is shown that both models are well predicted the reactor behavior#
