The present invention is a dehydrogenation catalyst in which tin, lanthanum and potassium are supported as a platinum group metal and an active auxiliary metal on an alumina support, and lanthanum is supported in a molar ratio of 0.00015 to 0.0059 to the weight of the support, and the molar ratio of tin to platinum is 0.32 to 1.6. , A molar ratio of potassium to platinum is 4.5 to 12.2, and a dehydrogenation catalyst and a method for preparing the same, which have an acid point amount of 20 to 70 μmol KOH / g catalyst when the catalyst is titrated with KOH. The resulting dehydrogenation catalyst can provide high hydrocarbon conversion and selectivity and performance stability, improved coking resistance and ease of coking removal. |
