ABSTRACT:
Catalysts, in particular for the detoxification of automobile exhaust gases, are prepared by a process in which the active components and the promoters are applied onto a carrier by vapor deposition under very greatly reduced pressure. The carriers used are advantageously in the form of nets or woven fabrics.
The catalyst fabrics coated by vapor deposition are pressed together to form catalyst packets for installation in the reactor, and the shape of the catalyst packets is adapted to the flow conditions in the reactor.
