Abstract

In search of a more effective process of ethane oxidative hydrogenation, different operation modes (thermal and microwave heating) are compared. The catalyst Mo₁-V_0.3-Te_0.13-Nb_0.11-O_x was prepared by hydrothermal synthesis and characterized by a set of physicochemical methods (XRD, N₂ adsorption, SEM, EDX). The direct microwave heating of the catalyst layer is proposed as an alternative way of energy-saving ethane-to-ethylene oxidation by a Mo-V-Te-Nb-O_x system. A substantial decrease in the reactor temperature upon the microwave-assisted process is accompanied by extremely high catalyst selectivity, which remains at a very high level of 98+%.

Keywords: catalyst Mo-V-Te-Nb-Ox; ethane; ethylene; microwave heating; oxidative dehydrogenation.
