Patent ID: 7101525

Claim:
Catalytic device for the implementation of a reaction in a gaseous medium at high temperature, comprising: at least one textured material ( 1 ) which is effective as a catalyst for said reaction, one support comprising one ceramic structure ( 3 ), which makes possible the passage of gases, said structure ( 3 ) having a corrugated face ( 6 ), so that the increase in surface area (β) produced by the corrugations with respect to a flat surface is between about 1.1 and 3, and at least equal to the increase of surface area (α) calculated for saw tooth corrugations according to a formula α=√{square root over ((4h 2 +d 2 ) )}/d in which h represents the height of each corrugation and d the distance between two corrugations, said textured material ( 1 ) being positioned so that it is held against the corrugated face ( 6 ) of said structure ( 3 ) and follows the form thereof.
