    摘要： 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.

    摘要： Methods and systems are provided for converting methane in a feed stream to acetylene. The method includes removing at least a portion of carbon dioxide from a hydrocarbon stream. The hydrocarbon stream is introduced into a supersonic reactor and pyrolyzed to convert at least a portion of the methane to acetylene. The reactor effluent stream may be treated to convert acetylene to another hydrocarbon process. The method according to the invention provides certain aspects includes controlling the level of carbon dioxide in the hydrocarbon stream and in a fuel stream that is first sent to a combustion zone and then to the supersonic reactor. The results of removal of carbon dioxide include maintaining the shock location in the supersonic reactor and maintaining the acetylene yield without the production of undesired products such as carbon monoxide.
