Summary: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 degrees centigrade (° C.) to about 2,500° C. by adding a heat sink gas to the carrier gas before the reaction zone, where the heat sink gas is different than the fuel and the oxygen. Methane is added to the carrier gas in the reaction zone, and a shock wave is produced in the reaction zone by adjusting a back pressure such that the methane reacts to form acetylene.
