Abstract: <PICT:0692504/IV (b)/1> <PICT:0692504/IV (b)/2> Apparatus for performing electro-chemical reactions by passage of electric current through conductive particles, e.g. carbon immersed in a liquid hydrocarbon to generate intermittent arcs between adjacent particles which are thereby set into motion, comprises rigid surfaces 7 set up in the liquid to act as baffles extending to or located at a substantial height above the rest level of the particles to restrict motion of the particles in one or more directions.  The apparatus may be used for the production of acetylene and other hydrocarrbon gases from hydrocarbons as in Specification 661,105.  The barriers comprise two series of slats 7 inwardly inclined in a frame 6 on legs 8 resting on a framework 2 supporting a layer of conductive particles in liquid.  The gases escape up through the louvres to an outlet 4 and the particles fall back to the framework 2 which, as in Specification 661,105, comprises spaced rectangular carbon rod electrodes 11 spaced by wood or like non-conducting rods with slots between them to allow particles reduced in size to fall to the bottom of the tank containing the liquid, whence the particles are removed. The baffles may comprise intersecting vertical partitions parallel to two adjacent sides of the rectangular frame 6 forming a cellular structure dipping into the liquid and so limiting horizontal motion of the particles.  This structure may be wood and rest on the electrode framework 2 or be supported above it by short legs. Motion of the particles may also be limited by mounting the square carbon rod electrodes 11 on stips 9 of wood slightly spaced to allow worn carbon particles to fall between them, the carbon rods preferably having transverse semi-circular channels 12 in their bases to allow some particles to pass therethrough.  Fresh carbon particles may be added at 5, and excess liquid may be removed at 3.ALSO:<PICT:0692504/III/1> <PICT:0692504/III/2> Apparatus for performing electrochemical reactions by passage of electric current through conductive particles, e.g. carbon immersed in a liquid, e.g. a hydrocarbon to generate intermittent arcs between adjacent particles which are thereby set into motion, comprises rigid surfaces set up in the liquid to act as baffles located at or extending to a substantial height above the rest level of the particles to restrict motion of the particles in one or more directions.
