- Аннотация: Highly selective and active phases in the ethane dehydrogenation were formed on the inner wall of stainless-steel reactor after its long-term using in the process at 650-750°C. The conversion of ethane at 650 °C reached up to 40% with ethylene selectivity closed to 90%. Fe-Cr-Ni and Fe-Cr oxides catalysts supported on carbon were created for CO2–mediated oxidative dehydrogenation of ethane (ODE) based on SR-XRD analysis of the inner wall of the steel reactor. In the case of Fe-Cr-Ni/C catalyst, the ethylene selectivity decreased and the catalyst was rapidly deactivated by coke deposits. On Fe-Cr/C catalyst, the ethylene selectivity was 82% and ethane conversion was above 20% at 700 °C. It was found that phase FeCr2O4 forms on the surface of Fe-Cr/C catalyst, which, as we assume, is responsible for high stability of the catalyst and its high selectivity of ODE with CO2.
