Emission of volatile organic compounds (VOCs) into the atmosphere is a great environmental issue because it has harmful effects on the ecosystems, the human health and animals. Hence, numerous scientific researches relate to the development of new methods and techniques to reduce their emissions into the environment. It is difficult to achieve this goal because of the increasing number of their emissions and catalytic oxidation is one of the most effective methods for this purpose. In the theoretical part of this work a review of literature related to the topic is given with particular emphasis on catalytic oxidation and perovskites as potential catalysts used for this purpose. The experimental part of the paper presents the results of the catalytic oxidation of toluene over an powdered perovskites catalysts (LaFeO3 and LaMnO3). Perovskite catalysts were prepared using citric method, while experimental measurements were done in the laboratory fixed bed reactor. Toluene was chosen as the representative of aromatic volatile organic compounds. Catalytic oxidation of toluene over LaFeO3 as a catalyst was preformed under various temperatures (100-300 °C) and space times. Space times inside the reactor were changed by changing the total flow rate of reaction mixture under constant mass of the catalyst (0.05 g). All measurements were performed at the constant initial concentration of toluene (210.43 ppm in nitrogen) and constant volume ratio of reaction mixture and air which was used as an oxidant (20:3). For comparison purpose, the activity of LaFeO3 was compared to the activity of LaMnO3 which was previously investigated in the same experimental system. It was found out that both catalysts show satisfactory activity and stability. However, LaMnO3 was found to be better catalyst because it allowed very high conversions at relatively low temperatures (< 280 °C).
