The invention discloses a dehydrogenation catalyst. The dehydrogenation catalyst uses modified alumina as a carrier, uses Pt as an active component, and uses Ga-containing perovskite as an auxiliary agent; the mass percentage of Pt in the dehydrogenation catalyst is 0.1 % to 0.5%, and the mass percentage of Ga is 0.4% to 3.1%. In addition, the present invention also provides a method for preparing the above-mentioned dehydrogenation catalyst and the application of the catalyst in dehydrogenation of alkanes to olefins. The preparation method of the present invention is simple, and the dehydrogenation catalyst prepared by the preparation method has High catalytic performance; the dehydrogenation catalyst of the present invention has the characteristics of high catalyst activity, anti-coking and good stability, the preparation method is simple and easy to implement, and has wide application prospects. |
