  • Method for catalytic dehydrogenation of hydrocarbons using carbon dioxide as a soft oxidant
    Patent number: 6958427
    Abstract: The present invention relates to a method for catalytic dehydrogenation of alkylaromatic hydrocarbons and more particularly, to a method for catalytic dehydrogenation of alkylaromatic hydrocarbons using carbon dioxide as a soft oxidant in the presence of a heterogeneous catalyst comprising both vanadium and iron, which allows operation at a lower reaction temperature due to improve thermodynamic equilibrium and provides an enhanced conversion of hydrocarbons and energy saving.
