The invention relates to a catalytic reactor including: at least one first architecture/microstructure including a ceramic and/or metal cellular architecture having a pore size of 2 to 80 ppi and a macroporosity of more than 85%, and a microstructure having a grain size of 100 nm to 5 microns, and skeleton densification of more than 95%, and a catalytic layer; and at least one second architecture/microstructure including a spherical or cylindrical architecture having a pore size of 0.1 to 100 &#x3bc;m and a macroporosity of less than 60%, and a microstructure having a grain size of 20 nm to 10 &#x3bc;m and a skeleton densification of 20% to 90%, and a catalytic layer; the first and second architecture/microstructure being stacked inside said reactor.

Catalytic reactor including one cellular area having controlled macroporosity and a controlled microstructure and one area having a standard microstructure

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.
