Abstract

A catalytic, gas treating apparatus in which a unitary ceramic catalytic element having gas flow passages therethrough, is positioned within a metallic casing in a manner providing a space between the casing and the catalytic element. A resilient member which is compressible both radially and longitudinally is positioned around the catalytic element in said space to resiliently hold the catalytic element. A plug member is positioned at least partially in said space, and, for instance, around the catalytic element at opposite end portions of the catalytic element, in a manner which longitudinally compresses said resilient member to a substantial extent to increase the holding force exerted on the catalytic element by the resilient member and thereby inhibit axial movement of the catalytic element during use. The device avoids the necessity of providing end flanges extending from the casing and overlapping the periphery of the end faces of the catalytic element for the purpose of minimizing axial movement of the catalytic element, and, as a result, essentially all of the gas flow passages remain available to the flow of the gas to be treated and there is maximum catalyst utilization.
