Abstract :

Light olefins (ethylene, propylene, and butylene) can be produced from methanol through non-oil route. In this study, HZSM-5 catalyst was synthesized by hydrothermal method and characterized using X-ray diffraction (XRD), Field emission scanning electron microscopy (FE-SEM), N2 adsorption-desorption (BET), Fourier transform infrared spectroscopy (FT-IR), and NH3 temperature programmed desorption (NH3-TPD) analysis. The catalysis included microsphere morphology which led to mesoporous structure formation and acceleration of diffusion. Based on characterization, the catalysis represented high crystallinity, high surface area and appropriate acidity properties. The results showed that the catalysis provided high methanol conversion (99.5%), selectivity of light olefins (82%), and long-term catalytic lifetime (72h). In order to increase the production yield, suitable reaction groups and kinetics in consistent with the catalysis performance was determined and methanol to olefin (MTO) process was simulated. The simulation results showed well agreement with the experimental data. Optimization of kinetic and operational parameters of MTO resulted in high methanol conversion and light olefins selectivity as 100 % and 94.1 %, respectively. The catalysis performance in the MTO process under the optimized operational conditions was confirmed the simulation results which indicated practicality of applied simulation and optimization
