In situ CO2 reactivation of FeCrOx/C catalyst in the oxidative dehydrogenation of ethane to ethylene

Catalyst FeCrOx/C in the course of oxidative dehydrogenation of ethane with carbon dioxide to ethylene at temperatures of 600–700 °C was found to undergo in situ regeneration with CO2 to give a stoichiometric amount of CO by the Boudoir–Bell reaction with the surface carbonized material.
