Abstract
The invention discloses a catalyst for preparing methylacrolein in a fixed bed, a preparation method and application. The composition of the catalyst is Mo Bi Fe < c > Co < d > Cu < e > Mg < f > C < sg > O < x >, a is equal to 12, 0lt; blt; 3.5, 0 lt; clt; ct; 3, 0lt; dlt; 8, 0lt; lt, lt; 3, 0lt; flt; 3, 0lt; glt; 2; and x is the number of oxygen atoms required for forming the composite oxide. In the preparation process of the catalyst, salts or oxides containing Mo, Bi, Fe, Co, Cu, Mg and Cs are added to form a dispersion system, and meanwhile, a complexing agent, a polymer monomer and a cross-linking agent are added into the dispersion system step by step or directly, so that the purposes of controlling the morphology, granularity and uniformity of the catalyst and further improving the activity and selectivity of the catalyst are achieved.
