<p>A method for preparing 1,3-butadiene by using a solid catalyst having a core-shell structure is provided to realize excellent catalytic activity, and to obtain a high yield of 1,3-butadiene. A method for preparing 1,3-butadiene comprises carrying out oxidative dehydrogenation of C4 cut-III generated from a naphtha cracking process in the presence of a solid catalyst having a core-shell structure and represented by the formula of [BinAaOx][(100-z)%EeFefNigMomOy + z%SiO2], wherein A is at least one element selected from the group consisting of B, P and Mo; E is at least one element with a valence of 2; n is 0.001-2, a is 0.001-3, e is 0.001-3, f is 0.01-5, g is 0.1-5, and z is 0-90, when m is 1; and each of x and y is a value defined by the valences of the other elements in the core portion and the shell portion.</p> |
