Abstract

PURPOSE:To obtain a strong catalyst body with thin wall thickness by a method wherein a metal net prepared by forming slits mutually on a metal plate and opening said slits is used as a core metal of a honeycomb shaped catalyst body. CONSTITUTION:As a honeycomb like core body of a honeycomb shaped catalyst suitable as a denitrating catalyst or the like, slits are formed mutually from an end portion of a metal plate 6 and the said slits are successively opened to provide openings 7. Thereby, because a cross area of a core body is changed to a bent shape, if a catalyst layer is supported thereto in such an extent that the said catalyst layer is slightly thicker than a metal thickness, the said catalyst layer is hardly fallen away. Thusly formed core body is layered to prepare a honeycomb shaped catalyst body. The wall thickness of this catalyst body can be thinned and the said catalyst body has high strength.
