Abstract: Methods and systems are provided for converting methane in a feed stream to acetylene. The method includes processing the acetylene to form a hydrocarbon stream having vinyl chloride. 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 is be treated to convert acetylene to other hydrocarbon processes. The method according to certain aspects includes controlling the level of carbon monoxide in the hydrocarbon stream to limit downstream side reactions in the downstream processing units.

Abstract: An improved process for the removal of acetylene from a hydrogen chloride stream in which the acetylene is converted to vinyl chloride by contact with a hydrochlorination catalyst, the improvement comprising, prior to contacting the stream with the hydrochlorination catalyst, contacting said stream with a catalyst comprising a noble metal, preferably of the platinum group, or salt or oxide thereof, supported or unsupported, at a temperature of between about 50.degree. and about 200.degree. C. and a pressure between about 8 and about 20 bar absolute.
