PROBLEM TO BE SOLVED: To provide a dehydrogenation catalyst applicable to the production of alkenes by dehydrogenating alkanes which maintains high catalytic activity and selectivity over a long period even under high temperature reaction conditions. SOLUTION: A catalyst is prepared by a method in which at least one alkaline metal selected from the group consisting of platinum, tin, the group IA elements, and the group IIA elements of the periodic table is supported on a composite carrier in which zinc oxide is supported on γ-alumina carrier at least 150 m2/g in surface area, at least 0.55 cm3/g in pore volume, and 90-200 angstrom in average pore diameter in which the volume of pores 90-200 angstrom in pore diameter occupies at least 60% of the total pore volume, and the support of the alkaline metal is performed prior to that of tin. |
