  • Publication number: 20250249425
    Abstract: A high voltage discharge between two electrodes generating a plasma is disposed within a reactor chamber. Hydrocarbon gas and conductive liquid are passed over one or more electrodes, such that the conductive liquid cools the electrodes and avoids fouling. Such a discharge may result in hydrogen gas and additional carbon containing coproducts which may be used, released, or sequestered.

  • Patent number: 12358821
    Abstract: A method of waste treatment includes treating partially-dewatered matrix with a first electron-beam radiation dose. The treated partially-dewatered matrix is transferred to a digester where the treated partially-dewatered matrix is subjected to anaerobic digestion. Biogas is recovered from the treated partially-dewatered matrix during the anaerobic digestion. The treated partially-dewatered matrix is dried and subjected to a second electron-beam radiation dose.

  • Publication number: 20250043196
    Abstract: Disclosed are example efficient circuits that produce spark discharges for hydrocarbon conversion (or treatment of other mixtures) using a high-voltage rectified DC supply to discharge a capacitor (either internal or external) across a two-electrode gap, optimized to minimize waste energy by operating in a constant current, approximately-constant current, or constant power mode. The circuits may operate off of a standard electrical supply line (e.g. 120 VAC or 240 VAC, 60 Hz, single-phase or multi-phase). The disclosed approach is scalable to any number of discharge gaps while maintaining similar pulse characteristics and electrical efficiency.

  • Publication number: 20250019598
    Abstract: A high voltage discharge generating a plasma wave front is disposed within a headspace over an oil-containing liquid in order to create various chemical changes within the headspace, and ultimately within the liquid in order to inactivate various microbes, synthesize new chemicals, speed separation of a mixture, and aid in oil extraction. Such a discharge may be repeated at an optimum duration and duty-cycle to maximize the chemical effects of the non-equilibrium plasma at a substantially lower temperature than for an equilibrium plasma.

  • Patent number: 12104625
    Abstract: In an embodiment, the present disclosure pertains to a cavitation generation device that includes a dactyl plunger rotatable about an axis between an open position and a closed position and a propus socket having a channel. The propus socket is rigidly mounted below the dactyl plunger, and the dactyl plunger is received into the propus socket when the dactyl plunger is in the closed position. The cavitation generation device can also include a torsion spring that biases the dactyl plunger into contact with the propus socket. In another embodiment, the present disclosure pertains to a method of inducing a cavitation including biasing a dactyl plunger via a torsion spring, and rotating the dactyl plunger, by action of the torsion spring, into a propus socket. The propus socket includes a nozzle-shaped channel. The method further includes ejecting a socket cavity volume through the nozzle-shaped channel thereby inducing a cavitation event.
