Metathesis of Ethene and Decene to Propene over a WO3/SiO2 Catalyst

Metathesis between decene and ethene to propene over a WO3/SiO2 catalyst was studied. The dependency of the conversion of decene, selectivity to propene, and working lifetime of the catalyst on ethane‐to‐decene molar ratio and temperature was evaluated. Low temperature was found to be favorable to t...

Description
Summary:Metathesis between decene and ethene to propene over a WO3/SiO2 catalyst was studied. The dependency of the conversion of decene, selectivity to propene, and working lifetime of the catalyst on ethane‐to‐decene molar ratio and temperature was evaluated. Low temperature was found to be favorable to the production of C6–C9 olefins, while high temperature enhanced C10+ olefins. The working lifetime of the catalyst decreased with the weight hourly space velocity. The optimum reaction conditions for the metathesis process of decene and ethene to propene were determined. An obvious induction period was found to exist in the metathesis reaction. Metathesis between decene and ethene to propene over a WO3/SiO2 catalyst is proposed as a new route for the production of propene. The effects of reaction conditions on the conversion of decene, selectivity to propene, and working lifetime of the catalyst were investigated. An obvious induction period for the metathesis reaction was found.
