Catalytic reactor including a cell-like structure and elements optimizing the contact thereof with the inner wall of the reactor

摘要

The invention relates to a catalytic reactor including: a reaction chamber; at least one catalytic structure made up of at least one catalytic cell-like architecture having outer dimensions at most 10% smaller than the inner dimensions of the reaction chamber; an annular space between the inner wall of the reaction chamber and the cell-like architectures; and at least one second structure positioned in the annular space, selected from among: a) a fibrous structure, or b) a structure including at least one metal collar clasping at least one portion of the cell-like architectures and supporting metal fins.

1. A catalytic reactor comprising:
a reaction chamber; at least one catalytic structure comprises at least one catalytic cellular architecture having external dimensions at most 10% smaller 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 metal fibrous structure made of a nickel alloy based on NiCrO, NiCrAlO or NiFeCrAlO, orb) a structure comprising at least one metal collar tightly encircling at least one portion of the cellular architectures and supporting metal fins.
