文摘
- •
Metathesis and isomerization between ethylene and n-butene on W-based catalyst were summarized under different conditions.
- •
Mechanism of metallacyclobutane intermediate formation from trans/cis-2-butene and W atoms was proposed.
- •
Thermodynamic calculation and experiments under different conditions were conducted to deeply analyze the complicated reactions.
- •
The results will guide the development of more active catalysts for propylene production.
