Document Type and Number:
WIPO Patent Application WO/2019/134715
Kind Code:
A1
Abstract:
Disclosed are a (methyl) acrolein oxidation catalyst and a preparation method therefor. The catalyst has a composition represented by the following formula: Mo12PaCsbVcDeOf is a heteropolyacid salt main catalyst; C is a nano carbon fiber additive, and Z is a carrier thermal conduction diluent; Mo, P, Cs, V, and O represent the elements of molybdenum, phosphorus, cesium, vanadium, and oxygen, respectively; D represents at least one element selected from copper, iron, magnesium, manganese, antimony, zinc, tungsten, silicon, nickel, and palladium; a, b, c, e, and f represent the atomic ratio of each element, a=0.1-3, b=0.01-3, c=0.01-5, e=0.01-2, and f being the atomic ratio of oxygen required to satisfy the valence of each of the described components; x and y represent the weights of the main catalyst and the carrier thermal conduction diluent Z, and y/x=11.1-50%; t represents the weight of the nano carbon fiber, and t/x=3-10%. x(Mo12PaCsbVcDeOf)+tC/yZ
