In apparatus for the production of acetylene by the partial combustion or pyrolysis of hydrocarbons, the reaction space is separated from the quenching space by a partition having heat insulating material on the reaction space side, there being at least one opening to permit passage of reactants. In a preferred embodiment the partition is circular, positioned centrally in a circular passage, leaving an annular opening for the reactants. The side adjacent to the reactor may be shaped, e.g. paraboloidal or conical in cross-section, to channel the gases, and the side adjacent to the quench is preferably provided with a cooling system, the inlets and outlets forming part of the supporting structure. The quench may be an atomizer giving a conical spray directed into the annular passage, and the partition and atomizer may be movable relative to each other and the reaction space. Specifications 703,721, 908,274 and 912,445 are referred to.
