CATALYTIC PROPERTIES OF MOLYBDENA-ALUMINA CATALYSTS

The catalytic properties of molybdena-alumina catalysts reduced in hyd rogen were studied in the function of the reduction temperature, i.e. in the function of the extent of reduction. The deuterium exchange rea ction of benzene was used as model catalytic reaction. It was conclude d that the reaction rate constant and the multiplicity factor decrease d with the extent of reduction parallel with the change in the extent of dehydroxylation of the catalysts.
