Sažetak
One of the major air pollutants that give rise to harmful health and environmental effects are volatile organic compounds (VOCs) emitted from many of anthropogenic sources. Among existing destructive VOCs removal methods, catalytic combustion is the most convenient one due to low reaction temperatures that lead to lower NOx and CO emissions. Catalysts usually used in this process are supported or unsupported noble metals and transition metal oxides or their combinations. Recently, many efforts have been made on the utilization of the low-cost and environment-friendly raw materials, such as manganese oxide combined with nickel, which have been investigated in this research. In this study toluene has been chosen as a representative volatile organic compound, since it contains aromatic ring which cannot be easily degraded. Catalysts based on the mixed manganese oxides were synthesized by the co- precipitation method and characterized using different instrumental techniques (such as DSC, FTIR, SEM, etc.) Monolithic Mn-Ni catalyst was prepared using the washcoating method. Catalytic combustion of toluene was carried out both in the fixed bed reactor (catalyst in the powder form) and in the metallic monolith reactor. Reaction was performed at different reaction temperatures and different total flow rates of the reaction mixture (23-100 cm3/min). It was revealed that the manganese-nickel mixed oxide catalysts show good catalytic activity, achieving a complete oxidation of toluene in the temperature range of 230-350 °C, depending on the space time inside the reactor, toluene inlet concentration and the type of catalyst used.
