Title

Synthesis and Characterization of MFI Zeolite Nanosheets for Optimizing the Dominant Operational Conditions of Methanol to Propylene Process

Pages

  51-73

Abstract

 Nanosheets of MFI zeolite were successfully synthesized by hydrothermal method and were properly characterized by XRD, FE-SEM, EDX-dot mapping, TEM, FT-IR, N2 adsorption/desorption, NH3-TPD, ICP-AES and TGA techniques. The characterizations of MFI Zeolite Nanosheets suitably confirmed well synthesized MFI nanostructure, superior specific surface area (695. 96m 2. g-1 ) and great mesopores volume. Currently, the major concern in commercialized technologies of Methanol to Propylene (MTP) process is to discover the best Operational Conditions for maximizing propylene selectivity. Therefore, in present investigation the effectiveness of more significant Operational Conditions such as reaction temperature, methanol molar percent in feedstock and methanol WHSV on propylene selectivity was considered. For first time, conventional Response Surface Methodology and an artificial neural network model coupled with genetic algorithm were appropriately employed to optimize MTP Operational Conditions. For providing the data bank of Optimization, MTP reaction was carried out over the synthesized MFI Zeolite Nanosheets at various Operational Conditions. It was concluded that neuro-genetic method showed more reliable performance in optimizing MTP Operational Conditions with R 2 value of 0. 9998. Furthermore, time on stream examination was conducted over MFI Zeolite Nanosheets at optimal Operational Conditions which were suggested by neuro-genetic approach. At optimal Operational Conditions the catalytic life-time was sufficiently enhanced (101h).
