| 摘要 |
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. |
