    Abstract: A process for continuously upgrading heavy oil to produce light hydrocarbon gases which are recycled in the process as a carrier gas used in spark-discharge hydrocarbon cracking within the process. The process also produces light hydrocarbon liquids which are used to upgrade the heavy oil. An apparatus for continuously upgrading heavy oil to produce light hydrocarbon gases which are recycled in the as a carrier gas used in spark-discharge hydrocarbon cracking within the apparatus. The apparatus also produces light hydrocarbon liquids which are used to upgrade the heavy oil.

    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: An apparatus for converting heavy hydrocarbons to light hydrocarbons includes an inlet capable of supplying a pre-foaming mixture comprising a hydrocarbon to be processed and a processing gas, wherein the processing gas is dissolved in the hydrocarbon to be processed; a foam generator configured to receive the pre-foaming mixture at a first pressure, compress the pre-foaming mixture to a second pressure that is higher than the first pressure by routing it through a nozzle; and generate a foam by allowing the pre-foaming mixture at the second pressure to expand in a chamber at a third pressure that is lower than the first or second pressures; a plasma reactor, wherein the plasma reactor is capable of receiving the foam and comprises at least one pair of spark gap electrodes capable of subjecting the foam to a plasma discharge to yield a processed mixture; and an outlet capable of receiving the processed mixture.
