Preparation and application of Ba/ZSM-5 zeolite for reaction of methyl vinyl ether and methanol

• Ba modified H-ZSM-5 (Ba/ZSM-5) is synthesized.
• The modified catalysts remarkably enhance the olefin selectivity.
• The addition of MVE can significantly promote the propylene selectivity.

The ZSM-5 zeolite is widely used to catalyze the reactions of methanol to olefins. Herein, we have prepared the H-ZSM-5 doped with barium (Ba/ZSM-5) using incipient wetness impregnation method. The Ba modified catalysts were used to catalyze a new reaction of methanol with methyl vinyl ether to improve the selectivity of ethylene and propylene (C2= + C3=). The reaction catalyzed by Ba doped H-ZSM-5 shows higher propylene selectivity over H-ZSM-5. The reaction mechanism is discussed.

The figure illustrates that Ba modified H-ZSM-5 enhances propylene selectivity and the addition of methyl vinyl ether to methanol promotes propylene selectivity, respectively.Figure optionsDownload as PowerPoint slide
