Abstract
Characterisation of surface acidity of the Re2O7/Al2O3 catalyst by inf rared spectroscopy and ammonia thermodesorption reveals that the initi ation and the good processing of the metathesis reaction is essentiall y governed by Lewis acidity. This strongly supports the role of Lewis acidity quantified by pyridine and lutidine adsorption, which is exalt ed by the increase of the rhenium content and the calcination temperat ure and the concomitant increase of the metathesis activity.
