Key words: Mo—V—Nb—Te—O-catalysts, oxidative dehydrogenation, ethane, ethylene, molecular oxygen
The process of oxidative dehydrogenation of ethane (ODE) at elevated pressure on mixed oxide catalyst MoVNbTeOx has been investigated. It was found that when the reaction is carried out at 280 °C with an increase in pressure from 0,1 to 10,0 MPa, the proportion of the total amount of reacted oxygen consumed for the formation of ethylene decreases from 100 to 68 %, which may indicate an increase in the role of chemisorbed oxygen in the ODE process at high pressure. In this case, the productivity for ethylene at 280 °C and 10,0 MPa higher compared to the value obtained at 360 °C and 0,1 MPa.
