<p>22Shell catalytic converter made of a hollow cylindrical carrier body and a catalytically active oxide mass applied to the outer surface of the carrier bodyAbstract5An eggshell catalyst consisting of a hollow cylindrical support body of length 2 to10 mm, external diameter 4 to 10 mm and wall thickness Ito 4 mm, and an eggshell, applied to the outer surface of the support body, of catalytically active oxide material of the general formula I,10MOIMID 4W0 to 3CU0.81, 1.0(10 to 4 X20 to 400n (I)in which the variables are each defined as follows:15 X1 = one or more elements of the alkali metals and alkaline earth metals; X2 = one or more elements from the group of Si, Al, Ti and Zr; andn = the stoichiometric coefficient of the element oxygen, which Is determined bythe stolchlometric coefficients of the elements other than oxygen and the charges thereof in I.Figure 1</p> |
