    摘要: A process for converting carbon dioxide and hydrogen into a product stream comprising carbon monoxide, water and hydrogen by introducing carbon dioxide, hydrogen and oxygen into a reaction vessel, and performing a reverse water gas shift reaction at elevated temperature, wherein



    (a) no catalyst is present in vessel
    (b) gas stream comprising carbon dioxide, a hydrogen and an oxygen rich gas stream are introduced into the vessel in separate feed streams,
    (c) the hydrogen and oxygen rich gas stream being introduced in close vicinity of each other, via burner comprising coaxial channels wherein gases undergo a combustion reaction, providing the heating energy required for the reverse water-gas shift reaction; and
    (d) the temperature in vessel is in the range of 1000 to 1500° C. by varying the molar ratio of hydrogen to oxygen.




    It is useful in reducing the carbon footprint of certain industrial technologies, and in production of synthesis gas.
