Abstract:
Two H-[B]-ZSM-۵ zeolites were synthesized using silicic acid and aerosil ۲۰۰ as the silica sources with the seed-assisted hydrothermal technique. The catalytic performance of zeolites was studied in methanol to propylene (MTP) reaction at ۴۸۰ ᵒC using a fixed-bed tubular reactor. To compare, an industrial ZSM-۵ zeolite from Sud-Chemei was also studied and referenced. The synthesied catalysts were characterized with a variety of investigating methods including XRD, FE-SEM, N۲ adsorption-desorption, FT-IR, and XRF analyses. The results revealed that the zeolite prepared by silicic acid (SA) proposed a high yield of propylene in MTP reaction (۱۳۶ g/g catalyst) much higher than the other studied catalysts. The activation time of SA was also noticeable (up to ۱۱۰ h in methanol WHSV of ۸ h-۱ and feed MeOH/H۲O of ۹۰/۱۰), which was ۱.۵ times that of the industrial catalyst
