CARRIER FOR CERAMIC HONEYCOMB STRUCTURE CATALYST AND CERAMIC HONEYCOMB STRUCTURE CATALYST CONVERTER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a carrier having no fine cracks in its outer peripheral end and improved in assembling properties when housed in a metal container, and to provide a catalyst converter capable of developing capacity when mounted on a car by eliminating the clogging of cells. SOLUTION: In the carrier housed in the metal container through a grasping member, chamfering of 1-not above 3 mm is applied to the outer peripheral end of the carrier over at least either one of the length H along the outer peripheral surface of the carrier from the end surface thereof and the height (h) along the end surface of the carrier from the outer peripheral surface thereof. The angle from the end surface to the outer peripheral surface of the chamfering is 10-80 deg., preferably, 10-45 deg. and 1-3 times a cell pitch. The catalyst converter uses this carrier.
