The Effect of Pressure on the Oxidative Dehydrogenation of Ethane with Molecular Oxygen over a MoVNbTeOx Mixed Oxide Catalyst

The process of oxidative dehydrogenation of ethane (ODE) at an elevated pressure over a MoVNbTeOx mixed oxide catalyst is studied. It is found that when the reaction is carried out at 280 degrees C, the fraction of the total amount of reacted oxygen consumed for the formation of ethylene decreases from 100 to 68% with the increase in pressure from 0.1 to 10.0 MPa, which may indicate an increase in the role of chemisorbed oxygen in the ODE process at a high pressure. Here, the productivity with respect to ethylene at 280 degrees C and 10.0 MPa is higher in comparison with the value obtained at 360 degrees C and 0.1 MPa.

Automated summary

The process of oxidative dehydrogenation of ethane (ODE) over a MoVNbTeOx mixed oxide catalyst was studied, and it was found that the role of chemisorbed oxygen increases at high pressure. Additionally, the productivity of ethylene is higher at high temperature and high pressure.
