Abstract: Volatile organic compounds (VOCs) are responsible for environmental problems and may affect human health. Several treatment technologies minimize VOCs emissions; among those, catalytic oxidation appears as a promising alternative. In this study, a pilot-scale catalytic reactor was developed and the influence of process parameters on toluene degradation were investigated. Inlet gases were heated by electrical resistances and the catalyst employed was a honeycomb shape commercial automotive catalyst (Umicore, model AFT). Toluene degradation higher than 99% was achieved for several conditions and temperature showed to be the most important process variable for it. For all concentrations, it was observed that when increasing temperature led to a decrease on the space time. At 800?ppmv, varying from 543?K to 633?K, the space time decreased from 0.121?s to 0.08?s, respectively. At 1600?ppmv for the same temperature range, space time was reduced from 0.098?s to 0.040?s, respectively. At 2400?ppmv, varying from 543?K to 633?K, space time decreased from 0.081?s to 0.048?s. The catalytic reactor developed proved to be efficient for VOCs treatment, showing a high potential of application at industrial emission sources
