A fluid-treatment apparatus has a coil structure, a first circuit formed by a rectifier diode and a capacitor in parallel connection, a second circuit formed by a first coil wound on a first section of the coil structure and a second coil wound on a second section of the coil structure, and a third circuit formed by a third coil wound on the second coil and a fourth coil wound on a third section of the coil structure. The first and second coils have a first winding direction, and the third and fourth coils have a second winding direction opposite to the first winding direction. The first and second coils are a first alternate-current (AC) input terminal and the anode of the rectifier diode. The third and fourth coils are connected to a second alternate-current (AC) input terminal and the cathode of the rectifier diode.

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.

Provided is a method for upgrading pyrolysis oil through seawater electrochemical pretreatment of biomass and use thereof. The method includes: (1) crushing and sieving a biomass raw material to obtain a crushed biomass raw material, adding the crushed biomass raw material to a salt solution and mixing to be uniform to obtain a reactant mixture; performing an electrolytic reaction on the reactant mixture under conditions of stirring and an external voltage of 5-15 V for 2-8 hours to obtain a product mixture; after the electrolytic reaction, subjecting the product mixture to a suction filtration, collecting a filter cake, washing the filter cake and drying to obtain a pretreated biomass, and (2) subjecting the pretreated biomass obtained in step (1) to a pyrolysis reaction at a temperature of 400-600° C. for 30-90 minutes in a protective gas atmosphere, and collecting a pyrolysis oil by an organic solvent.

Embodiments of the disclosure include processes using microwave heating to promote the separation of components of crude oil. In some embodiments, microwave-heated water may be used to heat the interphase between the gas phase and the oil phase of a crude oil stream to promote the separation of sulfur (for example, H.sub.2S) and light end components of the crude oil stream. In some embodiments, microwave-heated water may be used to heat the interphase between the oil phase and the water phase of a crude oil stream to promote the separation of water, salt, or both of the crude oil stream. Systems having a microwave unit to provide microwave-heated water to crude oil stream are also provided.
