Abstract:	The numerical analysis of H₂ production during partial oxidation of H₂S $/>H<sub>2</sub>O in a plug-flow reactor at atmospheric pressure and a rather low temperature (<em>T</em><sub>0</sub> = 500 K) was conducted, when the oxidizer (oxygen or air) was preliminarily activated by an electrical discharge with different values of reduced electric field and input energy. It was shown that a significant hydrogen yield in flow reactor can be obtained only after ignition of the mixture. The ignition delay length depends on the reduced electric field <em>E</em>/<em>N</em> and input energy <em>E</em><sub><em>s</em></sub> in the discharge and is minimal at <em>E</em>/<em>N</em>～8–10 Td for the discharge in oxygen and at <em>E</em>/<em>N</em>～4–10 and 120–150 Td in air discharge, when O<sub>2</sub>(<em>a</em><sup>1</sup>Δ<sub>g</sub>) mole fraction in the discharge products is maximal.
