CATALYTIC REACTOR COMPRISING A CATALYTIC ALVEOLAR STRUCTURE AND ELEMENTS OPTIMIZING THE CONTACT OF THIS ALVEOLAR STRUCTURE WITH THE INTERNAL WALL OF THE REACTOR

摘要

Catalytic reactor comprising: a reaction chamber; at least one catalytic structure consisting of at least one catalytic alveolar architecture of external dimensions less than 10% less than the internal dimensions of the reaction chamber; an annular space between the inner wall of the reaction chamber and the cellular architectures; at least one second structure positioned in the annular space, chosen from: a) a fibrous structure, or b) a structure comprising at least one metallic collar enclosing at least a portion of the cellular architectures and supporting metal fins or c) a powder or a mixture of metallic and / or ceramic powders.
