3- 3- A METHOD FOR MANUFACTURING THREE DIRECTION-HONEYCOMB MODULE FOR SOLID CATALYST SUPPORT OR DISPERSANT AND THREE DIRECTION-HONEYCOMB MODULE MANUFACTURED FROM THIS METHOD

摘要

The present invention is a new concept of three-way honeycomb (3D-honeycomb) used as a catalyst dispersion and a support in a low-pressure reactor to reduce the pressure loss in the reactor generated by the adsorption or chemical reaction using a solid catalyst Method for manufacturing a module and a three-way honeycomb module manufactured therefrom,;The honeycomb module manufactured by flattening the metal mesh plate and the corrugated plate that corrugates the plate, or by alternately arranging them, is washed with hydrochloric acid, sulfuric acid, nitric acid and hydrofluoric acid or caustic soda, and calcined at high temperature to form an oxide film on the wire surface After forming, wash-coating with a catalyst slurry solution formed by adding a catalyst, an adhesive, and optionally an adhesion aid and a pore control agent to water, and when the catalyst is attached to the plate and the corrugated plate, they are alternated between the plate and the corrugated plate. The three-way honeycomb module;Compared with the conventional ceramic honeycomb, the surface area is larger and the flow direction is not only a channel, but also an irregular flow passage through the holes between the nets in the perpendicular direction to form a three-way turbulent flow to the reactant catalyst surface. Since the diffusion rate is improved, the reaction efficiency in the low pressure difference reactor can be greatly improved.
