Abstract: The features of catalytic ignition of 2H₂ + O₂ and (70% H₂ + 30% C₂H₆) + air mixtures over Pd wire are established. It is shown that the catalytic wire or foil is heated unevenly before ignition: initial ignition centers always appear. With sequential ignitions, a clearly observed ignition center changes its location on the wire with every succeeding ignition.

Keywords: surface, catalytic, ignition, hydrogen, hydrocarbon, oxidation, speed cinematography.
