Abstract:
A method for producing a silica-supported catalyst comprising Mo, V. Nb, and a component X (Sb and/or Te) to be used in a vapor phase catalytic oxidation or ammoxidation of proprane, comprising the steps of: (I) preparing a raw material mixture solution by mixing Mo, V, Nb, component X, a silica sol, and water; (II) obtaining a dry powder by drying the raw material mixture solution; and (III) obtaining a silica-supported catalyst by calcining the dry powder, wherein the silica sol contains 10 to 270 wt ppm of nitrate ions based on SiO2.
