Abstract
1281406 Methane oxychlorination process STAUFFER CHEMICAL CO 21 July 1969 [2 Aug 1968 5 March 1969] 36532/69 Heading C2C A methane oxychlorination process comprises (a) reacting a gaseous material comprising methane, an oxygen-containing gas and, as chlorinating agent, hydrogen chloride and/or chlorine in a reaction zone in the presence of a fluidized oxychlorination catalyst to produce a gaseous superheated effluent containing chlorinated methanes, unreacted chlorinating agent, non-condensable gaseous material including methane, and entrained solid material; (b) passing the effluent to a quenching zone where it is desuperheated and separating the entrained solid material therefrom; (c) passing the desuperheated effluent to a condensation zone to separate a condensate comprising a high-boiling fraction of the chlorinated methanes and hydrochloric acid from the remaining gaseous material, which contains the non-condensable material including methane and a lowboiling fraction of the chlorinated methanes, and separating said condensate from the remaining non-condensable gaseous material; and (d) separating a stream comprising the lowboiling fraction of chlorinated methanes from the remaining non-condensable gaseous material including methane, and recycling at least a portion of the chlorinated methanes to step (a).
