The manuscript we propose is devoted to a cheaper method of hydrogen-containing gas obtaining without contain the toxic CO gas by oxidizing natural gas with hydrogen peroxide at a lower temperature compared to existing processes of converting methane into synthesis gas without using any catalysts. This process was executed within a flow quartz reactor at temperatures of 860–900⁰C using a 10–35% aqueous solution of hydrogen peroxide. Due to the hydrogen peroxide inducing effect, complete natural gas conversion into hydrogen-containing gas was achieved with the yield of hydrogen (74%) and CO₂ (24.5%) without CO gas at T = 880⁰C with a 15% hydrogen peroxide solution, which makes it possible, after separating CO₂ without secondary conversion of CO, to use the obtained pure hydrogen in the energy sector and as a feedstock for the synthesis of chemical compounds, in particular, ammonia. The free-radical chain mechanism of methane conjugated oxidation is proposed, that the intermediate products of chain branching are CH₂O, and . Based on the presented mechanism, the kinetic equation of the reaction is derived, which experimentally confirmed.
