Abstract
Catalytic purification device for purifying air or gas by heat treatment with a catalyst. The catalyst is carried on a patterned strip or membrane that is folded in accordion style, forming two groups of parallel flow channels with simple connections for incoming and outgoing flows. Good heat economy is achieved by heat exchange between the incoming and outgoing flow of gases.
