Document Type and Number:
WIPO Patent Application WO/2017/130909
Kind Code:
A1
Abstract:
Provided is a fluid bed ammoxidation reaction catalyst which includes silica and a metal oxide, and in which a composite of the silica and the metal oxide is represented by general formula (1), namely Mo12BiaFebNicMgdCoeCefCrgZnhXiOj/(SiO2)A (In formula (1): X is selected from the group consisting of K, Rb, and Cs; 0.1≤a≤1, 0.5≤b≤4, 0.5≤c≤6.5, 0.2≤d≤2.5, 0.5≤e≤7, 0.2≤f≤1.2, g≤0.05, h≤4, and 0.05≤i≤1 are satisfied; A represents the silica content (mass%), and satisfies 35≤A≤48; and the values of α, β, and γ which are respectively calculated by formula (2), namely α=1.5a/(1.5(b+g)+c+d+e+h), formula (3), namely β=1.5(b+g)/(c+d+e+h), and formula (4), namely γ=e/(c+d+h), satisfy 0.03≤α≤0.12, 0.1≤β≤0.7, and 0.2≤γ≤4).
