Thermodynamics analysis of propane dehydrogenation oxidation to propylene
The equilibrium constant and conversion of propane dehydrogenation oxidation are calculated.Relation of dehydrogenation equilibrium conversion,hydrogen-burning rate and reaction heat is analyzed.It is found that the technique of dehydrogenation oxidation is good for increasing equilibrium conversion of propane.Propane dehydrogenation equilibrium conversion is as increase as hydrogen-burning rate.The hydrogen-burning rate should be greater than 48.6% to ensure energy coupling when reaction temperature is 923 K.The technology theory of propane dehydrogenation oxidation is that oxidation reheat is instead of the traditional superheated steam reheat.
