Catalysed filter based on biosoluble fibers
Catalyzed filter consisting of a filter body of bio-soluble fibers catalyzed with a catalyst comprising oxides of vanadium and titanium, wherein the total concentration of alkali metals in the filter body is less than 3000 ppm by weight and/or the total concentration of alkali earth metals in the filter body is less than 20% by weight.
1. Catalysed filter consisting of a filter body of bio-soluble fibers catalysed with a catalyst comprising oxides of vanadium and titanium, wherein total concentration of alkali metals is greater than zero, but less than 0.1% by weight and the total concentration of alkali earth metals in the filter body is greater than zero, but less than 10% by weight.
2. The catalysed filter of claim 1 , wherein the bio-soluble fibers are selected from the group of calcium-magnesium-silicates.
3. A method of removal of particulate matter and nitrogen oxides, dioxins and carbon monoxide from gases comprising the step of utilizing the catalysed filter of claim 1 for the removal of particulate matter and at least one of nitrogen oxides, dioxins and carbon monoxide from gases.
4. A method of removal of particulate matter, dioxins and carbon monoxide from gases comprising the step of utilizing the catalysed filter of claim 2 for the removal of particulate matter and at least one of nitrogen oxides, dioxins and carbon monoxide from gases.
5. The method of claim 3 , wherein the temperature of the gasses is less than 450° C.
6. The method of claim 4 , wherein the temperature of the gasses is less than 450° C.
