Abstract

The invention relates to a process and devices for carrying out the process for purifying gases, exhaust gases, vapours and brines which are contaminated with undesirable chemical substances or are mixed with these at relatively high concentrations, by photocatalytic reactions which take place on the surface of catalysts. The catalysts (1) are situated in a fixed bed or a fluidised bed on catalyst supports. In the fluidised bed, the catalysts themselves can act as catalyst support. Catalyst supports and catalysts are situated in a closed system through which the substrate to be purified is passed. In the fixed-bed catalyst principle, the catalyst support/catalyst system continuously or discontinuously passes through a wash zone (12) for washing off the mineralisation products formed. The reaction is induced by photons of short-wave light of a wavelength between 250 and 400 nm. <IMAGE>
