Abstract

Abstract

The thermodynamic analysis of the methane dry reforming process was conducted based on Gibbs free energy minimization principle using HSC Chemistry software. The effects of key parameters including reaction temperature, pressure, feed ratio (n(CH₄)/n(CO₂) mole ratio), O₂ and H₂O feed rates on equilibrium concentration of CO and H₂, n(H₂)/n(CO) mole ratio and carbon deposition were systematically investigated. It is shows that under conditions of 1137 K reaction temperature, 101.325 kPa pressure, n(CH₄)/n(CO₂) ratio of 1.20, n(O₂)/n(CH₄) ratio of 0.15, and n(H₂O)/n(CH₄) ratio of 0.07, the n(H₂)/n(CO) ratio is maintained at approximately 0.90, closely approaching the theoretical value of 1. The methane dry reforming enables both greenhouse gas reduction and high-value utilization, with the produced syngas serving as fuel and important chemical feed gas, making it a promising technology for achieving dual carbon goals.
