ABSTRACT:
Three-dimensional knitted catalyst gauzes made from noble metals have recently come into use for ammonia oxidation and other gaseous reactions. Particularly high yields accompanied by a stable course of the reaction and an extended service life of the catalyst gauze are achieved if the catalyst gauzes are knitted in two or more layers and the layers are connected together by pile threads. Important features are the largest possible number of pile threads per unit area and the alignment thereof as parallel as possible to the direction of flow of the reaction gases.
