Abstract: PURPOSE: A supported catalyst for direct dehydrogenation of n-butane is provided to suppress the generation of hard hydrocarbon by-product and to suppress the carbon deposition in a catalyst layer, thereby minimizing the inactivating phenomenon of a catalyst. CONSTITUTION: A supported catalyst for direct dehydrogenation of n-butane is a support catalyst in which the main catalyst of platinum and/or palladium and a copper co-catalyst are supported in an alumina support element. The support amount of the main catalyst is 0.1-5.0 weight% and the support amount of the co-catalyst is 0.1-5.0 weight% based on the total weight of the support catalysts. The alumina support element is one or more selected from gamma-alumina, eta-alumina, alpha-alumina, and theta-alumina. A preparing method of butenes includes the direct dehydration reaction of a normal-butane under the presence of the catalyst.
