The primary chemical reactions of methane are combustion, steam reforming to syngas, and halogenation. In general, methane reactions are difficult to control. Partial oxidation of methane to methanol, a more convenient, liquid fuel, is challenging because the reaction typically progresses all the way to carbon dioxide and water even with an insufficient supply of oxygen. The enzyme methan… WebThe Predictive Soave–Redlich–Kwong (PSRK) equation of state was used, as a thermodynamic model, to determine the changes in enthalpy (ΔH), entropy (ΔS), and Gibbs free energy (ΔG) at 800 °C for the main reaction of dry reforming of methane (DRM) and the side reaction of reverse water gas shift (RWGS) over each catalyst.
