Decomposition of gaseous trichloroethylene in a photoreactor with TiO2-coated nonwoven fiber textile

The decomposition of gaseous trichloroethylene by UV/TiO2 process in an ann ular photoreactor fixed with TiO2-coated nonwoven fiber textile was studied under various UV light intensities, humidities, oxygen contents and retent ion times of carrier gases. Experimental results indicated that the photoca talysis by UV/TiO2 process is technically feasible to decompose trichloroet hylene in air streams. A design equation combining the equations of continu ity and surface catalytic kinetics was developed for describing the decompo sition of trichloroethylene in air streams by UV/TiO2 process at various op erating conditions.
