Catalizador de deshidrogenación con poros portadores controlados

The present invention relates to a dehydrogenation catalyst, and more particularly, to a dehydrogenation catalyst which is a spherical platinum-based catalyst containing tin and potassium components and used in a dehydrogenation catalyst reaction of light hydrocarbons, such as propane and butane, in the range of C3 to C5, wherein the catalyst carrier has a pore size and a surface area controlled by heat treatment, and platinum and tin alloy components exist in an egg-shell form only to a certain depth from the surface of the catalyst. In the catalyst according to the present invention, the catalyst carrier is a mixture of gamma alumina and theta alumina and has a pore volume of 0.5-0.65 cc/g, the platinum dispersibility of the catalyst is 30-50%, and the platinum average particle size is 3-5 nm.
