The present invention relates to a method for preparing a magnesia-zirconia composite carrier for catalyzing oxidative dehydration of normal-butane by means of a sol-gel technique, a method for preparing a magnesium orthovanadate catalyst supported by the magnesia-zirconia composite carrier prepared thereby by supporting vanadium with the magnesia-zirconia composite carrier, and to a method for preparing normal-butene and 1,3-butadiene by using the catalyst. L'invention concerne un procédé de préparation de support composite de magnésie-zircone pour catalyser la déshydratation oxydative du butane normal au moyen d'une technique sol-gel, un procédé de préparation de catalyseur d'orthovanadate de magnésium supporté par le support composite de magnésie-zircone préparé par le procédé de préparation de l'invention par retenue de vanadium sur le support composite de magnésie-zircone, et un procédé de préparation de butène normal et de 1,3-butadiène au moyen d'un catalyseur.
