Abstract:In this paper, the conversion of methane to methanol on CuO/Al2O3 and Mo–CuO/Al2O3 catalysts in a plasma reactor was tested. A comparison between catalytic and plasma-catalytic systems had been made in tested temperature range of 50–300°C. Experimental results showed that plasma-catalytic system demonstrated a much better methane conversion than catalytic system in tested temperature range and Mo–CuO/Al2O3 revealed a higher catalytic activity than CuO/Al2O3 for methanol synthesis. Furthermore, an Arrhenius plot was made in order to deduce the mechanism of plasma activation, which revealed that the presence of plasma decreased the activation energy for both catalysts. In the case of Mo-CuO/Al2O3 catalyst, the enhanced activity for methanol synthesis was assumed due to the oxygen vacancies on Mo–CuO/Al2O3 catalyst, which can utilize plasma-induced species to improve the catalytic efficiency.
