  • Method for the treatment of comminuted matter by electrical discharge
    Patent number: 5702621
    Abstract: A method for the treatment of matter by plasma action to produce a glassy product. A plurality of electrode structures are positioned to define a reaction zone associated with the inter-electrode space. The inter-electrode space is conditioned (as by preionizing) and a series of discrete electrical discharges are produced throughout the reaction zone. In a preferred embodiment, the reaction zone is subjected to a sequence of discrete electrical discharges in a time interval less than the residence time of material to be treated within the reaction zone.

  • Plasmalysis treatment method for waste matter
    Patent number: 5626249
    Abstract: A method for the treatment of waste matter by plasma action. A plurality of electrode structures are positioned to define a reaction zone associated with the inter-electrode space. The inter-electrode space is conditioned (as by preionizing) and a series of discrete electrical discharges are produced throughout the reaction zone. In a preferred embodiment, the reaction zone is subjected to a sequence of discrete electrical discharges in a time interval less than the residence time of material to be treated within the reaction zone such that the waste material is pyrolyzed during its transit through the reaction zone.

  • Reactor for the treatment of particulate matter by electrical discharge
    Patent number: 5605640
    Abstract: A reactor and method for the treatment of matter by plasma action. A plurality of electrode structures are positioned to define a reaction zone associated with the inter-electrode space. The inter-electrode space is conditioned (as by preionizing) and a series of discrete electrical discharges are produced throughout the reaction zone. In a preferred embodiment, the reaction zone is subjected to a sequence of discrete electrical discharges in a time interval less than the residence time of material to be treated within the reaction zone.
