    Abstract: An internally cooled microwave stub tuner assembly with stubs having hollow ducts for receiving circulating cooling fluid while in operation. The microwave stub tuner assembly for a pyrolysis reactor includes at least one elongated hollow body plunger projecting into a waveguide cavity. Each of the hollow body portion of the plungers has at least one internal cooling duct for receiving a circulating cooling fluid and is adapted to be cooled by the circulating cooling fluid as the circulating cooling fluid enters the plunger, courses through each the internal cooling ducts and exits the plunger. Each plunger has a position adjuster for adjusting the position of the plunger within the waveguide cavity.

    Abstract: A method for controlling a microwave-assisted treatment including: injecting an initial substance into a cavity; propagating microwaves into the cavity, thereby obtaining a treated substance; extracting the treated substance; injecting part of the extracted substance into the cavity; measuring a complex reflection coefficient; comparing the measured complex reflection coefficient to a target value; when the measured complex reflection coefficient is different from the target value, measuring operation parameters; comparing the measured operation parameters to given operation parameters; when the measured operation parameters correspond to the given operation parameters: removing a contaminant from the treated substance prior to injection into the microwave cavity; and/or varying a quantity of a given element within the microwave cavity, the given element comprising a catalyst, a microwave receptor, a reagent or an additive.

    Abstract: There is described a microwave pyrolysis process for the depolymerization of plastic for the production of monomers, waxes and heavy oils including the steps of: a) steam purge of the plastic from about 0.5% to about 50% w/w of a catalyst, in a media; b) pyrolysis of the plastic and the catalyst in the media with a microwave (MW) for a time sufficient to allow generation of heat providing a thermal treatment between 300° C. and 650° C. through absorption of microwaves by the catalyst and the media. The catalyst includes a compound having a high dielectric loss at the frequency of the MW to absorb microwaves, transfer heat to the plastic and initiate a pyrolysis reaction.

    Abstract: A door assembly for a microwave reactor including a microwave waveguide to direct microwaves from an external microwave source to inside the microwave reactor, and having a waveguide interface for preventing backflow of a process gas into the waveguide; an inlet for entry of matter to be treated in the microwave reactor; a first seal at the periphery of the door assembly to sealably interface with a static front of the microwave reactor; a second seal inserted into a groove on an inside face of the door assembly to sealably interface with an opening of a microwave reactor drum, the groove having a width of about 12.9 inches (32.766 cm) divided by an integer, and the second seal configured to prevent solids and liquids from flowing outside of the reactor drum; and a ring choke to contact a choke arranged on the periphery of the opening of the reactor drum.
