The binding state of propylene responsible for partial oxidation reaction on cobalt molybdate catalyst has been identified to be the adsorbed state that is desorbable at the temperature of oxidation through TPD measurements. In addition, at low temperatures there is another weak reversible form of adsorption. The adsorbed state of the olefin responsible for complete oxidation and at times for partial oxidation could not be identified by TPD studies under some experimental conditions like high heating rates because of the simultaneous occurrence of the catalytic reaction through the participation of the lattice oxide ions.
