In order to develop a catalytic technology for processing coal mine methane into hydrogen-containing gas, thermodynamic analysis of methane tri-reforming (TRM) was carried out, and the influence of temperature (600–850 °C), contact time (0.04–0.15 s), linear feed rate (80–240 cm/min) and composition (CH4 / CO2 / H2O /O2 / He = 1: (0.3–0.5) : (0.2–0.5) : (0.1–0.3) : (2.9–3.2)) of the reaction mixture on the conversion of the initial reagents and target products in the TRM process in the presence of a supported Ni catalyst was studied. It has been shown that with an increase in the temperature of the TRM reaction from 600 to 800 °C the process performance improves (methane conversion: 36 → 94 %, carbon dioxide conversion: 57 → 97 %, hydrogen yield: 37→ 91 %,carbon monoxide yield: 44→ 94 %, molar ratio H2/CO: 1.5 → 1.7), and at a reaction temperature of 850 °C the process indicators are close to equilibrium values. It has been established that varying the O/C value and the composition of oxidants makes it possible to regulate the performance of TRM process. The optimal conditions for the TRM process were identified to achieve maximum efficiency of the catalytic processing of coal mine methane into hydrogen-containing gas: temperature – in the range of 800–850 °C, contact time – 0.15 s, linear feed rate –160 cm/min and molar ratio of reagents in the initial feed – CH4 / CO2 / H2O / O2 = 1: 0.5 : 0.2 : 0.25.
