Abstract
Provided is a catalyst for an oxidative dehydrogenation reaction that comprises: a porous support; a core portion supported on the porous support and containing a first zinc ferrite-based catalyst; and a shell portion supported on the core portion and containing a second zinc ferrite-based catalyst, in which the first zinc ferrite-based catalyst and the second zinc ferrite-based catalyst are different from each other.
Claims10
A catalyst for an oxidative dehydrogenation reaction, the catalyst comprising:
- a core part comprising a porous support, and a first zinc ferrite-based catalyst supported on the porous support;
- and
- a shell part comprising a second zinc ferrite-based catalyst supported on the core part,
- wherein the first zinc ferrite-based catalyst and the second zinc ferrite-based catalyst are different from each other, and
- wherein the first zinc ferrite-based catalyst has the following Formula 2 and the second zinc ferrite-based catalyst has the following Formula 3:
- (R1)aZnbFecOy Formula 2
- (R2)a′Znb′Fec′Oy′ Formula 3
- wherein in Formulae 2 and 3:
- R1 and R2 are each independently Cs, Ti, Zr, V, Nb, W, Cu, Ag, Cd, Sb, Ce, Cr, Mn, K, Co, or Mo, provided that R1 and R2 are different from each other;
- y and y′ are each independently 1 to 6;
- and
- a, b, c, a′, b′, and c′ are each independently more than 0 and 2.8 or less.
