Catalytic paraffin dehydrogenation for the production of olefins has been in commercial use since the late 1930s.During World War II,catalytic dehydrogenation of butanes over a chromia-alumina catalyst was practiced for the production of butenes which were then dimerized to octenes and hydrogenated to octanes to yield high-octane aviation fuel (1).More recently,platinum or modified platinum catalysts are used for selective conversion of paraffins to olefins.Important aspects in dehydrogenation entail attaining equilibrium or near-equilibrium conversions while minimizing side reactions and coke formation.
