Title: Apparatus for the production of gases consisting mainly of hydrogen and acetylene
IPC: C01B3/24
Filed: 1955-08-02
Abstract: <PICT:0783819/III/1> Gases consisting mainly of hydrogen and acetylene are produced from liquid hydrocarbons by generating intermittent electrical arc discharges in the hydrocarbons between the electrodes and auxiliary electrodes by means of an apparatus comprising a liquid-tight and gastight container with a supply means for the liquid hydrocarbon, and a discharge means for the gas mixture produced, an electrode arrangement consisting of at least 2 roller-shaped and rotatable main electrodes, each of which is rotatable about its own longitudinal axis spaced one from another together with an electrically non-conducting support for freely movable electrically conducting auxiliary electrodes, and also a driving means for the rotatable main electrodes and an electrical supply for the latter.  The main electrodes may be fixed, or one or both may be moved horizontally, in addition the support which may be slotted may be moved vertically.  In an example, liquid hydrocarbon from petroleum of boiling range 120-180 DEG  C. is introduced at 50 DEG  C. into a vessel 1 through an inlet 8, the vessel being fitted with cylindrical main electrodes 2 having a length of 150 mms. and a diameter of 115 mms. and being placed 35 mms. apart.  The auxiliary electrodes 3 are in the form of granules having a diameter of 7 mms. With a voltage of 550 volts and an energy consumption of 4-06 Kilowatt hours per standard cu. metre of gas produced, 1250 cu. metres per hour of gas is produced comprising 51.3 per cent of hydrogen and 36.7 per cent of acetylene.  Specification 661,105 is referred to.ALSO:<PICT:0783819/IV (a)/1> Gases consisting mainly of hydrogen and acetylene are produced from liquid hydrocarbons by generating intermittent electrical arc discharges in the hydrocarbons between the electrodes and auxiliary electrodes by means of an apparatus comprising a liquid-tight and gas-tight container with a supply means for the liquid hydrocarbon, and a discharge means for the gas mixture produced, an electrode arrangement consisting of at least 2 roller-shaped and rotatable main electrodes, each of which is rotatable about its own longitudinal axis spaced one from another together with an electrically-non-conducting support for freely movable electrically conducting auxiliary electrodes, and also a driving means for the rotatable main electrodes and an electrical supply for the latter.
