CATALYST STRUCTURE FOR PURIFYING EXHAUST GAS, RETICULUM USED THEREIN AND JIG FOR HANDLING RETICULUM

摘要

PROBLEM TO BE SOLVED: To provide a catalyst structure for purifying exhaust gas excellent in rigidity and catalytic efficiency and hardly being worn and deformed. SOLUTION: This catalyst structure is formed by laminating such many catalyst elements while interposing reticula 2, as are obtained by bending rectangular or square flat plates with a catalyst component deposited on the surfaces at prescribed intervals in the perpendicular direction with respect to a pair of the sides of the flat plate to alternately form planar parts and stepped parts or by curving the flat plates in corrugated forms at prescribed intervals to form mountain parts and valley parts alternately. In such a catalyst structure, the reticulum 2 has at least one belt-shaped reinforcing part 6 that a part of the meshes of the reticulum 2 is buried by a metal oxide.
