An electric arc heater, of the arc voltage 250V and the arc current 50A, was specially designed and built for the study of a steady arc performance and efficient productions of acetylene through the methane pyrolysis.
Hot gaseous reection products were quenched and sampled with a water-cooled probe. Under the conditions of the mass flow rate of methane 30liter/min and the electric input power 10-15 kW, major products in the quenched gas were acetylene and hydrogen. The concentration of the acetylene in the quenched samples reached as much as 23-35mol% on favorable conditions. This experimental results were found better consistent with the estimations calculated on the hypothesis of a chain reaction as to the methane pyrolysis, than the analysis based on the assumptions of equilibrium processes.
