摘要：

The oxidative dehydrogenation of ethane in the supercritical state into ethylene on MoVNbTOx oxide catalysts at the total pressure of an O-2-containing mixture of 100 atm was carried out. The high reaction pressure allowed us to decrease the temperature from 360 degrees C at 1 atm to 280 degrees C at 100 atm along with the increased productivity of C2H4 from 205 to 290 gC(2)H(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 Te.
