The present invention relates to a catalytic device for the implementation of a reaction in a gaseous medium at high temperature, such as, for example, the synthesis of HCN or the oxidation of ammonia, comprising: at least one textured material (1) which is effective as catalyst for the said reaction, a support (2) comprising at least one ceramic part (3), the structure of which makes possible the passage of the gases, the said part (3) of the said support (2) having a corrugated face (6), so that the increase in surface area (.beta.) produced by the corrugations with respect to a flat surface is at least equal to that (.alpha.) calculated for sawtooth corrugations and of between approximately 1.1 and approximately 3, the said textured material (1) being positioned so that it is held against the corrugated face (6) of the said part (3) of the said support (2) and follows the form thereof.
L'invention concerne un dispositif catalytique servant à exécuter une réaction dans un milieu gazeux à température élevée, telle que, par exemple, la synthèse de HCN ou l'oxydation d'ammoniac, ce dispositif comprenant: au moins un matériau texturé (1) efficace en tant que catalyseur pour ladite réaction, un support (2) comportant au moins une partie céramique (3) dont la structure permet le passage des gaz, ladite partie (3) dudit support (2) possédant une face ondulée (6), de sorte que l'augmentation de la zone superficielle (.beta.) produite par les ondulations par rapport à une surface plate est au moins égale à celle (.alpha.) calculée pour des ondulations en dents de scie et est située approximativement entre 1,1 et 3, ledit matériau texturé (1) étant placé de façon à être retenu contre la face ondulée (6) de ladite partie (3) dudit support (2) et à en suivre la forme.
