Oerftde those laid down in these patent applications optimal dimensions of the bee-weave-like framework are also ideally suited to solving the problems mentioned here.

Furthermore, it is within the meaning of the invention that the honeycomb-like structure of the trotter or the catalytic converter is produced according to the method identified by the inventor and according to the devices identified in patent applications 0-2 650 X / 39a ⁴ and D 43 63O X / 39a ⁴ . In particular, deformable materials that can be hardened after deformation have been proposed for the present purpose:

The solidification is after deformation in the sense of Patent applications D 35 848 X / 39a, D 37 230 X / 39a, D 42 65O X / 39a ^ and D 43 630 X / 39a4 preferably by drying, Pre-firing and post-firing carried out.

Such marked geometric shapes for catalytic converters, or their carrier bodies, are suitable suggestion devices especially for the already mentioned afterburning of exhaust gases from the Verhrennkraftraaachinen. An exchange this catalytically active, honeycomb-like structural body is quick and safe, for example to be carried out at every petrol station "

It is inserted into an easily exchangeable body 2, which is provided with a thermal insulation 3. The body 2 can be connected to the exhaust line 4 through the flange 5. The exhaust gases flow in the direction of the arrows 6. As is known, these must be provided with fresh air and, if necessary, initially heated so that the catalytic converter "starts". This fresh air supply and heating device ¹¹ ^ ind in. Fig. 1 is not shown. The post-oxidation then takes place within the honeycomb-shaped catalytic converter 1. The continuous honeycomb channels ensure a very low flow resistance
