Abstract (en)
[origin: WO2014086813A1] The invention relates to a catalyst which is obtainable from a catalyst precursor comprising a catalytically active multimetal oxide which contains molybdenum and at least one further metal and is of the general formula (I) Mo12BiaFebCocNidCreX1 fX2 gOx,in which the variables have the following meaning: X1 = W, Sn, Mn, La, Ce, Ge, Ti, Zr, Hf, Nb, P, Si, Sb, Al, Cd and/or Mg; X2 = Li, Na, K, Cs and/or Rb, a = 0.1 to 7, preferably 0.3 to 1.5; b = 0 to 5, preferably 2 to 4; c = 0 to 10, preferably 3 to 10; d = 0 to 10; e = 0 to 5, preferably 0.1 to 2; f = 0 to 24, preferably 0.1 to 2; g = 0 to 2, preferably 0.01 to 1; and x = a number which is determined by the valency and frequency of the elements in (I) that are different from oxygen, characterized in that the catalyst has the shape of a hollow cylinder, wherein the inner diameter is 0.2 to 0.8-times the outer diameter and the length is 0.5 to 2.5-times the outer diameter, and in that the catalyst precursor does not contain pore formers.
