Ammoxidation catalyst for propylene, manufacturing method of the same catalyst, ammoxidation method using the same catalyst

A method for preparing an ammoxidation catalyst for propylene comprising:

• preparing a first precursor solution comprising a Mo precursor,
• preparing a second precursor solution comprising a Bi precursor, a Fe precursor, an A precursor, wherein A is one or more elements of Ni, Mn, Co, Zn, Mg, Ca, and Ba, and a B precursor, wherein B is one or more elements of Li, Na, K, Rb, and Cs, or a second precursor solution comprising a Bi precursor, a Fe precursor, an A precursor, wherein A is one or more elements of Ni, Mn, Co, Zn, Mg, Ca, and Ba, a B precursor, wherein B is one or more elements of Li, Na, K, Rb, and Cs, and a C precursor, wherein C is one or more elements of Cr, W, B, Al, Ca, and V,
• mixing the first and second precursor solutions such that a molar ratio of metals satisfies stoichiometric molar ratio of Chemical Formula 1,
• supporting the mixture of the first and second precursor solutions on a silica carrier,
• drying the silica carrier in which the mixture of the first and second precursor solutions is supported, and
• calcining the dried material:
• Mo12BiaFebAcBdCeOx [Chemical Formula 1]
• in the Chemical Formula 1,
• A is one or more elements of Ni, Mn, Co, Zn, Mg, Ca, and Ba,
• B is one or more elements of Li, Na, K, Rb, and Cs,
• C is one or more elements of Cr, W, B, Al, Ca, and V, and
• a to e, and x are respectively fractions of each atom or atomic group, wherein a is 0.1 to 5, b is 0.1 to 5, c is 0.01 to 10, d is 0.01 to 2, e is 0 to 10, and x is 24 to 48.
