The activity of several supported tungsten oxide catalysts for the metathesis of propene has been studied under temperature-programmed conditions.WO3/TiO2 was found to be active at moderate temperatures; its activity passes through a maximum when the reaction temperature is decreased from 670 to 450 K.WO3/ZnO is less active and its activity as a function of the reaction temperature goes through a maximum under certain conditions.In contrast to these catalysts and to the earlier reported behaviour of the well known WO3/Al2O3 catalyst, the activity of the WO3/SiO2 catalyst steadily increases for reaction temperatures up to 860 K.In this respect the WO3/SiO2-Al2O3 catalyst behaves like the WO3/SiO2 catalyst and not like the WO3/Al2O3 catalyst.The acidity of the supports has been determined by means of a temperature-programmed desorption technique, using t-butylamine as the adsorbed species.The results of this work do not suggest a relationship between the acidity of the supports and the activity for metathesis.
