Method of Producing Zirconia Carrier for Catalyst for Oxidative Dehydrogenation of n-Butane, Method of Producing Zirconia Carrier-supported Magnesium Orthovanadate Catalyst, and Method of Producing n-Butene and 1,3-Butadiene Using Said Catalyst

摘要

PURPOSE: A method of producing zirconia support for a catalyst for the oxidative dehydrogenation of n-butane, a method of producing magnesium orthovanadate catalyst supported on a zirconia support, and a method of producing n-butene and 1,3-butadiene using the catalyst are provided to stably implement the oxidative dehydrogenation of n-butane. CONSTITUTION: A method of producing zirconia support for a catalyst for the oxidative dehydrogenation of n-butane includes the following: a zirconium precursor and oxalic acid are dissolved in ethanol; a zirconium ethanol solution and an oxalic acid ethanol solution are prepared; the zirconium ethanol solution and the oxalic acid ethanol solution are mixed to synthesize zirconia; and the zirconia is separated from the ethanol solutions, and the separated zirconia is dried and thermally treated to prepare a zirconia support for a catalyst for the oxidative dehydration of n-butane.
