Abstract: PURPOSE: Provided is a mixed-catalyst comprising an iron-chromium-potassium oxide catalyst and an iron supported catalyst, which improves a fractional conversion and a yield in a dehydrogenation of aromatic hydrocarbon. CONSTITUTION: The mixed-catalyst comprises: the iron-chromium-potassium oxide catalyst consisting of 10-90wt% of iron oxide, 0-90wt% of chromium oxide, and 0.1-50wt% of potassium oxide; the iron supported catalyst, wherein the carrier is zeolite, activated carbon, gamma-alumina, or silica. The dehydrogenation is performed by reacting a diluted gas and the aromatic hydrocarbon in the molar ratio of 1:1-50:1 at a temperature of 500-700deg.C, wherein the diluted gas comprises carbon dioxide and steam in the volume ratio of 1:10-10:1.
