Thermodynamic Analysis of Isobutane Dehydrogenation Reaction

Abstract

The thermodynamic of isobutane dehydrogenation reaction was deeply investigated using most reliable literature data. Conversion and reaction mixture distribution at equilibrium was computed for various process conditions. Reaction enthalpy, ∆_R H_T^o , ranges between 122±1.1 and 123±1.2 kJ.mol-1 over the temperature (773.15 to 923.15) K where the equilibrium constant K_T value varies between 0.12±0.03 and 2.6±0.7. The reaction becomes thermodynamically favorable at temperatures higher than 873.15 K.
