Abstract

A useful apparatus for purifying gases, comprising a wrap-around box defining a closed space; means that define a gas inlet that communicates with the closed space; means that define an outlet for gas that communicate with the closed space; a first ceramic structure in the enclosed space and having a unitary skeleton structure with a plurality of gas inlets, a plurality of gas outlets, and gas flow paths through the skeleton structure from the gas inlets to the gas outlets, said first ceramic structure being placed in said wrapping box so that a space is provided between them; a first flange member adjacent to the periphery of a first end face of the first ceramic structure and spanning said space between said casing and said first ceramic structure; and a first compressed knitted wire member placed under compression between the first flange member and the first end face of the first ceramic structure to provide an elastic connection between the first flange member and the first end face of the first ceramic structure over the temperature range to which the apparatus is subjected.
