Abstract: Tropospheric volume elements enriched with vital elements and/or protective substances as well as procedures for their production and application. The term “vital elements” applies to all matter supporting the development of life within the earth's biosphere and the term “protective substances” means all those substances which contribute directly or indirectly to the prevention of harmful effects on the earth's biosphere and in particular on man. Tropospheric volume elements in the form of clouds which contain contaminants and which can escape from industrial facilities due to damage or malfunction are enriched with protective substances which prevent the organism from taking in radioactive elements and minimize the extent of the area affected by the clouds and possess additional warning and identification properties.

Abstract: The present invention relates to a method and pertinent apparatus for purifying gases, exhaust gases, vapors, and brines, which are contaminated with undesirable chemical substances or contain high concentrations of these substances, by means of photocatalytic reactions occurring on the surface of catalysts.The catalysts are situated in a fixed or fluidized bed on catalyst carriers. In fluidized beds, the catalysts themselves can serve as catalyst carriers. The substrates to be purified are fed through a closed system which contains the catalyst carriers and catalysts.In the fixed-bed catalytic method, the catalyst carrier/catalyst system continuously or discontinuously passes through a washing zone to remove the generated mineralization products. The reaction is induced by shortwave photons of wavelengths between 250 and 400 nm.
