An electric pulse fragmentation device and method are provided, the device comprising a pulse transformer, one or more buffer capacitors, a plurality of IGBT modules, a storage capacitor, a spark gap, and a fragmentation chamber, the spark gap being defined by spark gap first and second electrodes, the fragmentation chamber comprising fragmentation chamber first and second electrodes. The buffer capacitors are electrically connected to a voltage rectifier. The buffer capacitors are charged by electrical current received from the voltage rectifier. The IGBT modules control partial discharge of the buffer capacitors to permit and restrict current flow from the buffer capacitor to transformer primary windings for a duration of a control pulse. The storage capacitor is charged by electrical current from transformer secondary windings. The storage capacitor is adapted to discharge current across the spark gap to the fragmentation chamber electrodes. Raw material positioned between fragmentation electrodes can be fractured.

DEVICE FOR PYROLYSIS OF CARBONACEOUS MATERIALS AND METHOD
The device (100) for pyrolysis of carbonaceous materials (15) comprises a working chamber (2) comprising a non-magnetic wall (7) comprising an inner graphite lining (8); one or more electrodes (10, 11) adapted to be inserted within a carbon-based bedding (84); a solenoid coiled around the device exterior, the solenoid (51) adapted to create a magnetic field within the working chamber (2) such that when the solenoid (51) is energized, the carbon-based bedding (84) is caused to move; a lower solids outlet (83) comprising an airlock, the solids outlet (83) adapted to permit solids to exit the device (100); and a lower gas outlet (35) adapted to permit gaseous substances to exit after having traveled through the carbon-based bedding (85). The method comprises the steps of loading carbon-containing materials (15) into the working chamber (2); using the first and second electrodes (10, 11) to heat the carbon- containing materials (15) by passing electric current through the carbon-containing materials (15) without air access; collecting, cleaning and releasing gaseous pyrolysis products (18) produced by the heating.
