    Abstract

    The effect of catalyst-support interactions in the vanadia catalysed oxidation of benzene to maleic anhydride and carbon oxides has been studied. A range of alumina, silica and silica-alumina supports have been coated with various loadings of vanadia and have been characterised and tested. The kinetics of the oxidation reactions have been determined. The activity of the catalyst is found to depend on the surface area of the vanadia. The selectivity of the reaction is considerably lower for alumina supports than for silica-aluminas and silica. In the case of silica containing supports the selectivity of the reaction depends on the size of the vanadia crystallites.
