Abstract: It was found that the ignition temperatures of H₂–O₂ and H₂–CH₄–O₂ mixtures at a low pressure on heated Pd, Pt, Nichrome and Kanthal wires at 40Torr increase with a decrease in H₂ concentration; only a heated Pd wire shows the pronounced catalytic action. Numerical calculations allowed us to reveal the role of an additional branching step, viz. H+HO₂→2OH.

Keywords: ignition, temperature, hydrogen, methane, oxygen, heated wire, additional branching.
