Disclosed are a catalyst filter characterized in that catalyst particles which are made of titanium oxide and vanadium oxide or titanium oxide, vanadium oxide and tungsten oxide and whose diameters are between 0.01 and 1 .mu.m are carried by a filter made by weaving monofilaments of a glass fiber and/or of a catalytic fiber;

Catalyst filter and method for manufacturing a catalyst filter for

The present invention is directed to a method for treating an exhaust gas which comprises cooling an alkaline neutralizing agent powder and blowing the cooled powder into the exhaust gas in order to remove acidic gaseous components from the exhaust gas, and recovering the used alkaline neutralizing agent, cooling it, and utilizing it again in order to remove acidic gaseous components from the exhaust gas.

Method for treating exhaust gas

A filter medium for treating exhaust gases is described. The filter medium comprises a porous ceramic substrate, a pre-coat layer of a reaction aid and a layer of a solid material formed on one side of the substrate from which the exhaust gas is charged through the substrate, and a catalyst layer for eliminating nitrogen oxides formed on the other side of the substrate from which the exhaust gas is discharged. The filter medium may have a double-cylinder construction, in which the catalyst layer is formed on at least one side of a inner cylinder and the pre-coat layer and the solid material layer are formed on an outer side of an outer cylinder.
