The invention relates to a shell catalytic converter made of a hollow cylindrical carrier body having a length of 2 to 10 mm, an outer diameter of 4 to 10 mm, and a wall thickness of 1 to 4 mm, and shell made of a catalytically active oxide mass applied to the outer surface of the carrier body, said mass having the general formula (I): MO 12 V 2 to 4 W 0 to 3 CU 0,8 to 1,5 Χ 1 n 0 to 4 X 2 n 0 to 40 O n , where the variables having the following meanings: X 1 = one or more elements of the alkali and alkali earth metals; X 2 = one or more elements from group of Si, Al, Ti and Zr; and n = the stoichiometric coefficient of the element oxygen, which is determined by the stoichiometric coefficients of the elements other than oxygen and the charge numbers thereof in I. |
