Abstract
A fixed bed photocatalytic reactor has been designed and built with a UV
radiation source. TiO2 pellets were placed on the three fixed beds within the
reactor. Acetone was used as an indicator of volatile organic compounds (VOCs)
during the experiment. Under the flow rate of 12.75 l/min, the oxidation
efficiencies were obtained at four different concentrations of acetone laden gas
streams ranged from 40ppm to 250ppm. It was found that the lower the acetone
concentration of the untreated inlet gas, the higher the oxidation efficiency; the
obtained oxidation efficiency was in the range of 40-70% for various
concentrations of untreated gases. Two concentrations of toluene laden gas
stream were a
