Preparation of Experimental Membrane Reactor Tube by Adhesive Welding a Porous Membrane with a Non Porous Ceramic Tube and Coating with Glaze

A preparation process of reactor tubes by adhesive welding a porous mem-brane tube with non porous ceramic tubes and coating with glaze was developed for preparing an experimental inorganic ceramic catalytic reactor. Not only the difficulties, such as no flow across the membrane in non-reaction zone, and doping the catalyst exactly on the reaction zone, could be thoroughly solved, but also the cost of the membrane reactor could be reduced and the mechanical strength of the tubes would be improved by this method. Alumina and zirconia membrane tubes with the pore size of 200, 100, 50 and 20nm, two kinds of adhesives and four sorts of glaze materials were tested; The optimal technological conditions for preparing the membrane reactor tube were determined, by which the inorgranic membrane tubes with relatively high thermal stability, mechanical strength and inertia for reactions were prepared. The kinetic data for oxidative coupling of methane using the inorganic ceramic membrane reactor were successfully measured at high temperatures for more than 40 hours.
