1,198,866. Acetylene. MONSANTO CO. 11 Aug., 1967 [25 Aug., 1966], No. 36940/67. Heading C5E. Acetylene is produced by incomplete combustion of hydrocarbons, particularly natural gas, with oxygen in an apparatus (Fig. 1) comprising a mixing chamber 1 having inlets 2 and 3 for oxygen and hydrocarbon respectively, a reaction chamber 6 bounded by walls 8 and provided with quench means 9, the two chambers being separated by a gas distributor 4 comprising a plurality of parallel channels 5 interconnecting the chambers, said gas distributor also comprising a hollow inner chamber 10 surrounding said parallel channels and extending across the entire cross-section of the gas distributor, said hollow chamber having means 14 for supply of combustion supporting gas thereto and being in open communication with the reaction chamber by means of a plurality of straight conduits 13. Pilot flames are maintained at the points of exit of conduits 13 into the reaction chamber, though additional pilots may be provided on side-walls 8. The end of the gas distributor adjacent the reaction chamber is preferably formed of metal having fluid conducting conduits 15 therein (Fig. 2). Parallel channels 5 may contain devices for imparting a swirling motion to the gases passing through them.
