Abstract
The invention relates to a catalytic reactor including: at least one first architecture / microstructure (1) 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 (2) including a spherical or cylindrical architecture having a pore size of 0.1 to 100 [mu]m and a macroporosity of less than 60%, and a microstructure having a grain size of 20 nm to 10 [mu]m and a skeleton densification of 20% to 90%, and a catalytic layer; the first and second architecture / microstructure being stacked inside said reactor.
Description
technical field [0001] The subject of the present invention is a catalytic reactor comprising at least one organizational structure and at least one standard organizational structure comprising a catalytic reactor with controlled macroporosity and controlled microstructure. Ceramic or metal foam. Standard organization is understood to mean the organization commonly used by manufacturers of catalysts, ie drums, rods, beads, tablets, etc. Background technique [0002] The performance of fixed bed reactors, especially steam reforming reactors, is directly related to the structure of the catalytic bed. The structure of the catalytic bed is understood to mean the same or different organizational structures (drums, spheres, rods, etc.) of catalyst stacks in the relevant industrial reactors. Porous structures have not yet been developed on an industrial level. Various water-gas shift reactor stacks (reactors involved in the water-gas reaction) (continuous catalytic beds with the...
