Abstract
The present invention relates to a dehydrogenation catalyst in which a platinum-group metal, an assistant metal, and an alkali metal or alkaline earth metal component are supported on a carrier, wherein the molar ratio of platinum to the assistant metal is 0.5 to 1.49, and the catalyst has an acidity amount of 20 to 150 μmol KOH/g catalyst when it is titrated with KOH. The dehydrogenation catalyst according to the present invention may prevent coke formation from increasing rapidly when the hydrogen/hydrocarbon ratio in a dehydrogenation reaction is reduced, thereby increasing the productivity of the process. Accordingly, it makes it possible to operate the process under a condition in which the hydrogen/hydrocarbon ratio in a dehydrogenation reaction is reduced, thereby improving the economy of the process.
