Metathesis of ethene and 2-butene to propene on W/Al2O3-HY catalysts with different HY contents

Metathesis between ethene and 2-butene to propene is catalyzed by 10 wt.%W/Al2O3-xHY with various HY content at temperature 180 °C and pressure 0.1 MPa. Reaction and characterization results reveal that Brönsted acidity of catalysts and the interaction between W species and support simultaneously play their important roles in the reaction.
