    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 V AC, 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.

    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.

    Abstract: Provided is an approach for scaling up a multiphase plasma chemical reactor that uses gas bubble discharge in liquids. One example involves single spark gap discharge scale up systems and processes with suitable characteristic parameters. Scaling parameters are based on the size change of one spark gap. Another example involves scale-up systems and processes that can be applied to multiple spark gaps with multiple discharge modules and its dimension information. Numbers of modules and resulting device sizes could be based on required production rate and specific energy input. Applications allow for scaling up of any plasma chemical system or process with similar mechanisms and reactors, such oil treatment reactors.
