Abstract: There is provided a dehydrogenation catalyst for producing olefins from alkane gases, in which a metal active component is supported on an alumina carrier containing boron. There is provided a method for preparing a dehydrogenation catalyst for producing olefins from alkane gases. The method includes impregnating alumina in a boron-containing solution and calcining it to provide a boron-alumina carrier; providing a solution containing the metal active component; impregnating the boron-alumina solution in the solution containing the metal active component and drying it; and calcining the boron-alumina carrier on which the metal active component is supported at 700° C. to 900° C.
