Apparatus for a catalytic purification of flowing gas, comprising a housing adapted to be arranged in a gas flow path, which housing contains a gas-permeable support in the form of a knitted textile fabric folded to form a stack of contacting superimposed sheets in substantially parallel planes and made of heat resistant fibrous material on which a catalytically active material is applied, wherein the planes of the superimposed sheets are essentially parallel to the flow of gas such that the flow of gas is entirely parallel to the planes of the superimposed sheets and wherein at least a substantial portion of at least one surface of each sheet contacts at least a substantial portion of a surface of an adjacent sheet.
Apparatus for a catalytic purification of flowing gas, comprising:
- a housing means for conducting flow of gas;
- a gas-permeable, knitted textile fabric means, made of a heat resistant fibrous material and folded to form a stack of contacting superimposed sheets in substantially parallel planes wherein at least a substantial portion of at least one surface of each sheet contacts at least a substantial portion of a surface of an adjacent sheet, for passing the flowing gas entirely parallel to the planes of the superimposed sheets;
- and
- a catalytically active material on the fabric means.
A method for a catalytic purification of flowing gas, comprising:
- flowing a gas through a housing in a direction entirely parallel to a direction of planes of superimposed sheets of a gas-permeable, knitted textile fabric made of a heat resistant fibrous material, comprising a folded stack of the superimposed sheets in substantially parallel planes wherein at least a substantial portion of at least one surface of each sheet contacts at least a substantial portion of a surface of an adjacent sheet;
- and
- catalytically purifying the gas by contacting the gas with a catalytically active material on the gas-permeable, knitted textile fabric.
