The present invention relates to a catalyst for preparing 1,3-butadiene in which a transition metal compound is supported on regular mesoporous silica, and a method for preparing 1,3-butadiene using the same. Selectivity can be improved, and the selectivity and type of transition metal oxide can be used to improve the selectivity, and the high dispersing activity point due to the high surface area can increase the synthesis yield of 1,3-butadiene as well as regular meso It has a pore structure, which facilitates diffusion and mass transfer of reactants and products, and is not unbalanced, so that the entire active point can participate in the reaction evenly. Since the catalyst life is suppressed and the catalyst life is greatly improved compared to the conventional silica catalyst, the regeneration cycle is longer, resulting in process operation efficiency. It is possible to improve, it can be usefully employed in the preparation of 1,3-butadiene. |
