ABSTRACT:
There are provided shaped catalysts, particularly for the formation and/or equipping of reaction chambers with catalytically active surfaces, consisting of a structural reinforcing agent of ferrous metal, a layer of a heat resistant carrier material on the structural reinforcing agent as well as a catalytically active component on the carrier material; the body of the structural reinforcing agent consists of iron or steel and its surface is provided with a nonscaling, adhesive and anchoring enhancing aluminum/iron diffusion layer obtained by a tempering of aluminum coated iron or steel at a temperature between 600.degree. and 1200.degree. C. for at least one minute. There is also disclosed a process for making the catalysts.
