Toluene oxidation by microwave assisted catalysis over alumina supported mixed cobalt-manganese oxide catalyst

Popis výsledku v původním jazyce

This work is focused on the development suitable low cost catalyst for the microwave assisted catalytic oxidation of VOCs for future pilot technology. The series of nine single and mixed component cobalt and manganese oxides catalysts were prepared by impregnation of alumina with aqueous solutions of cobalt and manganese nitrates. These catalysts have been tested for the oxidation of toluene by innovative microwave heating, which can increase efficiency and reduce operating temperature. It has been observed a different heating rate of alumina or titanium oxide catalyst support and a different behaviour between single cobalt and manganese oxides on alumina support in microwave field. Mixed cobaltmanganese oxides are more reactive than a simple cobalt oxide. The addition manganese into precursor solution led to higher heating rate. Among the prepared catalysts, the mixed 10 wt% cobalt-manganese oxide catalyst in molar ratio 4:1 exhibited the best toluene conversion 70.4% at 240 °C.
