Abstract: Disclosed is a method for preparing butene from n-butane by direct dehydrogenation using a specific supported catalyst.When the supported catalyst of the present invention, wherein platinum, palladium or platinum and palladium as main catalyst and a copper cocatalyst are supported on an alumina support, is used to prepare n-butenes by direct dehydrogenation of n-butane, production of byproducts resulting from cracking and isomerization, deposition of carbon and inactivation of the catalyst are effectively suppressed and conversion ratio of n-butane and selectivity to n-butenes are remarkably improved.
