Abstract

Un aparato utilizable para tratar gases, que comprende: (a) una envuelta metálica que define un recinto y que tiene una entrada de gas y una salida de gas que comunican con dicho recinto; (b) un elemento catalítico de menor dimensión que dicho recinto y situado en la envuelta de una manera que proporciona un espacio que se extiende alrededor del elemento catalítico entre el elemento catalítico y la superficie interior de la envuelta, comprendiendo dicho elemento catalítico una estructura de cerámica de esqueleto de una pieza que tiene a su través caminos de flujo de gas; (c) un miembro elástico, flexible, que sujeta firmemente dicho elemento catalítico y situado entre el elemento catalítico y la superficie interior de la envuelta, siendo dicho miembro elástico compresible tanto radial como longitudinalmente con respecto a dicho elemento catalítico; y (d) al menos un miembro de tapón que está al menos parcialmente dentro de dicho espacio entre la superficie interior de la envuelta y la periferia del elemento catalítico, estando situado dicho miembro de tapón dentro de dicho espacio para comprimir longitudinalmente a dicho miembro flexible elástico lo suficiente como para sujetar dicho elemento catalítico contra movimiento axial durante su uso.
