Cfd Modeling For Selective Formation of Propylene From Methanol Over Synthesized Mn-Substituted Mfi Metallosilicate Catalyst

The high silica mn-substituted mfi metallosilicate catalyst with si/al molar ratio of 220 and si/mn molar ratio of 50 was successfully synthesized by hydrothermal method. the catalyst sample was appropriately characterized by xrd, fe-sem, edx, and bet techniques. the mn-substituted mfi metallosilicate has not been reported as the potential catalyst for methanol-to-propylene (mtp) reaction. the prepared catalyst was examined in the mtp reaction in the optimal operating conditions. furthermore, to elucidate the flow field of the mtp fixed bed reactor, a three-dimensional (3d) reactor model was developed. a detailed reaction mechanism that was proposed for the mtp reaction over the mn-impregnated mfi zeolite (mn/h-zsm-5) was properly employed. the reaction mechanism was integrated to a computational fluid dynamics (cfd) for simulating kinetics, energy equation, and the hydrodynamics of the mtp process, simultaneously. the component distribution during the implementation of the mtp reaction was also simulated as a function of time on stream. the cfd modeling results were validated by the actual data obtained over the mn-substituted mfi metallosilicate catalyst. with regard to the findings, the experimental data were in good agreement with the predicted values of the cfd modeling.
