Zusammenfassung:Methods and reactors are provided for producing acetylene. The method includes combusting a fuel with oxygen in a combustor to produce a carrier gas, and accelerating the carrier gas to a supersonic speed in a converging/diverging nozzle prior to the carrier gas entering a reaction zone. A nozzle exit temperature of the carrier gas is controlled from about 1,200° C. to about 2,500° C. Methane is added to the carrier gas in the reaction zone, and kinetic energy in the carrier gas is converted to thermal energy in the reaction zone to increase the temperature of the carrier gas such that the methane reacts by pyrolysis to form the acetylene.
