Abstract

Abstract

Based on the principle of Gibbs free energy minimization using HSC chemistry software, thermodynamic analysis of the CH₄/CO₂ reforming reaction process was performed. The effects of key parameters such as reaction temperature, pressure, feed ratio (n(CH₄)/n(CO₂) molar ratio), the inlet amounts of O₂ and H₂O, on the the equilibrium product distribution and reactant conversion were systematically explored. The results indicate that the conditions of 1137 K, 101.325 kPa, n(CH₄)/n(CO₂) = 1.20, n(O₂)/n(CH₄) = 0.10, and n(H₂O)/n(CH₄) = 0.07 are most favorable for CH₄/CO₂ conversion and H₂/CO generation. As an upstream reaction in numerous chemical synthesis chains, CH₄/CO₂ reforming effectively utilizes the two major greenhouse gases CH₄ and CO₂ to produce syngas (H₂/CO), an important chemical raw materia. These findings benefits the development of related industries and provide a useful reference for global climate sustainability.
