FIELD: chemistry.
SUBSTANCE: invention relates to method of obtaining acetylene by oxidative pyrolysis of methane in presence of oxygen-containing gas and catalyst, heated to temperature 750-1200°C by passing electric current through it. Method is characterised by the fact that as catalyst applied are oxides with perovskite structure of general formula Ba0.5Sr0.5Co0.8-xWxFe0.2O3-δ, wherein x = 0-0.1; δ = 0.4-0.6, moulded in form of tubes, methane is passed from outside of catalyst tube, and oxygen-containing gas - inside of catalyst tube.
EFFECT: application of claimed invention makes it possible to increase stability of catalyst and exclude formation of carbonaceous sediments on its surface, which increases acetylene output and ensures explosion safety of the process.
