Abstract

The gradually increasing demand on 1,3-butadiene (BD) requires alternative production routes. Catalytic oxidative dehydrogenation of 1- butene to BD using CO₂ as soft oxidant was proved as a potential process and thus systematically studied over Fe₂O₃/Al₂O₃ catalysts. It was found that the loaded Fe₂O₃ promotes oxygen mobility and modifies the surface acidity of Al₂O₃, leading to a higher 1-butene conversion and BD selectivity; the highest ones were obtained on 20 wt.% Fe₂O₃/Al₂O₃ at 600°C. The in situ Diffuse Reflectance Infrared Fourier Transform Spectroscopy studies revealed that CO₂ is essential to promote the activation of 1-butene on the Fe₂O₃ catalysts and thus BD production.
