Method for producing dehydrogenation catalyst, method for producing unsaturated hydrocarbon, and method for producing conjugated diene
A method for producing a dehydrogenation catalyst, comprising: a step of impregnating a carrier with a first solution having a tin source dissolved therein, so as to have tin supported on the carrier; and a step of impregnating the carrier with a second solution having an active metal source dissolved therein, so as to have the active metal supported on the carrier, wherein the tin source is at least one selected from the group consisting of sodium stannate and potassium stannate, and the active metal source has at least one active metal selected from the group consisting of platinum, ruthenium and iridium, and has no chlorine atom.
