Abstract
• Metathesis is a commercially successful process for the production of lower olefins . • An increase of the F content on support leads to significant increase of the propylene conversion. • The change in the support acidity doesn’t affect the structure of surface molybdenum forms. • Olefin metathesis can proceed under mild conditions on modified catalysts. • The strength of OH groups and Lewis acidity are the determining factors for propylene metathesis. Supported MoO 3 /Al 2 O 3 -F catalysts were synthesized and characterized by Raman, IR, and NMR spectroscopy. It was shown that support fluorination leads to partial substitution of surface OH groups with F which is accompanied by increases the strength of both LAS (Lewis Acid Sites) and residual bridging OH groups. But the change in the acidity doesn’t affect the structure of surface molybdenum forms. An increase of the fluorine content on γ-Al 2 O 3 up to 6 wt% leads to 4.7-fold increase of the propylene conversion in metathesis reaction (WHSV = 11 h −1 , T = 100 °C, p = 9 atm.) with selectivity above 95 %. The results prove that the support acidity plays an important role in the propylene metathesis. The catalyst modification method proposed here opens new opportunities for the improvement of classical metathesis catalysts.
