The effect of Si/Al ratio in the synthesis of B/H- ZSM-۵ catalyst in methanol to Propylene

A series of boron-containing H-ZSM-۵ zeolites with different Si/Al ratios between ۱۱۲ and ۱۵۲ wereprepared employing the hydrothermal method. The evaluation of catalytic performance in the methanol-topropylene(MTP) reaction shows that the catalyst with Si/Al equal ۱۳۲ illustrated the best lifetime and selectivityto propylene.
