Method for producing a microtubular reactor module

Disclosed herein is a method for producing a microtubular reactor module for use in microcatalytic reactor systems, the method comprising the steps of assembling and sealing a reactor frame around a microtubular honeycomb carbon material, using an adhesive; fabricating a chemical vapor deposition (CVD) system and coating a catalyst from a vaporized-catalyst precursor on a surface of the microtubular honeycomb carbon material in the chemical vapor deposition (CVD) system, the surface being in contact with fluid flow; and drying the coated microtubular honeycomb carbon material, and then reducing the nano-sized metal catalyst-coated surface of the carbon material in a reducing atmosphere.
