Abstract: The oxidative dehydrogenation of ethane in the supercritical state into ethylene on $\mathrm{MoVNbTeO_x}$ oxide catalysts at the total pressure of an $\mathrm{O_2}$-containing mixture of 100 atm was carried out. The high reaction pressure allowed us to decrease the temperature from $\mathrm{360^{\circ}C}$ at 1 atm to $\mathrm{280^{\circ}C}$ at 100 atm along with the increased productivity of $\mathrm{C_2H_4}$ from $\mathrm{205}$ to $\mathrm{290}$ $\mathrm{g_{C_2H_4}~h^{-1}~kg_{cat}^{-1}}$, respectively. Moreover, the higher pressure also prevents the destruction of M1 phase of the catalyst via the reduction of $\mathrm{Te}$.
