Abstract (en)

[origin: WO2004105921A1] Waste gas filtering using porous materials: organic (e.g. cellulose pulp from paper production) or inorganic (e.g. mineral wool waste) with water glass (Na2SiO3, nH2O) impregnation. According to the invention, this process binds pollution in the filter material and absorb carbon oxide in the hardening process. Plates, tube linings, bicurved planes, granulates or the like can be made of the filter material.
