Abstract: The propane dehydrogenation reaction was carried out in the presence of CO₂ on a Cr(3%)/SiO₂ catalyst under supercritical conditions. Dependences of the propane conversion, product selectivity, and olefin productivity on the C₃H₈:CO₂ ratio and reagent consumption were revealed. It was found that the application of supercritical conditions resulted in the increase in propylene productivity by a factor of three and overall olefin productivity by a factor of five as compared to a conventional reaction in the gas phase.

Keywords: supercritical carbon dioxide, dehydrogenation, carbon dioxide, propane to propylene, utilization of carbon dioxide..
