Abstract

La grille selon l'invention possède, dans son armure, des fils de différents diamètres, contenant les mêmes métaux précieux que ceux qui servent à la récupération des platinoïdes. Les fils de différents diamètres sont utilisés en fonction du type de processus catalytique. L'invention est particulièrement applicable à la récupération du platine au cours de la production de NO et de NH3 .
