The invention relates to a catalyst for isobutane dehydrogenation, which mainly solves the problem of low activity of dehydrogenation catalysts prepared in the prior art. The invention adopts a composite catalyst, which comprises the following components in parts by weight: a) 0.1-5 parts of Pt or its oxide; b)0.1 to 5 parts of Sn or an oxide thereof; c) 90-99 parts of a composite oxide M1-M2-Al-O carrier, wherein M1 is selected from a mixture of elements IIA and VB, and M2 is selected from at least one of lanthanide elements, so that the problem can be well solved, and the method can be used for industrial production of isobutene prepared by isobutane dehydrogenation. |
