| This invention relates to a device for producing cellulose which includes the following: a cooking reactor which contains sulfate alkali liquor and a lignocellulose material; a DC source and electrodes in contact with the sulfate alkali liquor; and a capacitor connected in parallel with the DC source. The electrodes in contact with the sulfate alkali liquor have a spark gap, and a switch is connected between the capacitor and the spark gap. The device is provided with two inductance coils and with an additional spark gap, connected serially with the main spark gap. A first plurality of the inductance coils' ends are connected between the additional spark gap and the capacitor, the second end of one inductance coil being connected between the main and the additional spark gaps, and the second end of the other inductance coil being connected between the switch and the main spark gap. The device is provided with an inductance coil, an additional capacitor and an additional spark gap, the latter being connected serially with the main spark gap. The additional capacitor is connected in parallel with the additional spark gap, the inductance coil being coupled by one end between the additional spark gap and the condenser and by the other end between the switch and the main spark gap. | ||||||

| A process for producing a work piece includes providing raw material which is cellulose-containing and fibrous, which is not any part of a tree, and which is selected from the group consisting of, crude plant fibers, pure cellulose, waste paper, and waste cardboard; adding water to the raw material; finely chopping the raw material in a machine by continuously grinding the raw material with a total energy expenditure of at least 0.5 kWh/kg, based on dry weight of the raw material, into a microfiber pulp having an increased internal fiber surface and an increased degree of interlinking; forming the microfiber pulp to provide a shaped green body; and drying the shaped green body by removing water therefrom to harden the shaped green body and form a work piece, wherein the shaped green body is hardened into the work piece by drying only without admixture of bonding agents to the microfiber pulp and without use of external pressure, and wherein the work piece has characteristics which depend on degree of grinding to produce the microfiber pulp and which range from (a) paper carton-like to (b) wood-like to (c) horn-like, the work piece having a specific gravity which ranges up to that of pure cellulose, 1.5. | ||||||
