Title:
MOLYBDENUM-VANADIUM COMPOSITE OXIDE CATALYST, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/103894
Kind Code:
A1
Abstract:
Disclosed are a molybdenum-vanadium composite oxide catalyst, a preparation method therefor and a use thereof. In the catalyst, X is selected from Nb, Sb, Te, Zn, Ca, and Bi; Y is selected from Nd, La, Ce, W, and Cu; and Z is selected from Cd, Sr, Sb, B, and Ni; a=1-20; b=0.05-10; c=0-5; d=0.01-4; e=0.01-5; g=0.05-15; h=0.01-5; i=0-4; j=0-3; f and k are values that satisfy each atomic valence state; and m/n is 0.5-5. The catalyst is obtained by the following method: (1) dissolving precursor compounds Mo, V, W, Cu and X by using a predetermined ratio, and drying to obtain the following formula A particles: MoaVbWcCudXeOf; (2) dissolving precursor compounds Mo, V, Y and Z by using a predetermined ratio to obtain a solution B of the following formula: MogVhYiZjOk; and (3) dispersing the A particles into the solution B, drying, and roasting to obtain a catalyst.
