NOVELTY - Process (P1) for reducing an organic-containing material into lower molecular weight gaseous hydrocarbons, liquid hydrocarbons and solid carbon constituents, comprises e.g.: (a) feeding a sample of the organic-containing material into an infeed system; (b) transferring the material into at least one microwave applicator (12); and (c) exposing the material in the microwave applicator to at least two sources of microwaves from a bifurcated waveguide to volumetrically reduce the material into the constituents, and a frequency of the microwaves of 894-1000 MHz and without an external heat source.    USE - The process is useful for: volumetrically reducing shredded scrap tires to constituents comprising hydrocarbon gas and carbon; shredded asphalt roofing shingles to constituents of at least hydrocarbon gas, carbon, and fiberglass; volumetrically reducing shredded computer waste to constituents of at least hydrocarbon gas, carbon, and metals; volumetrically reducing shredded scrap rubber to constituents of at least hydrocarbon gas and carbon; volumetrically reducing polychlorinated biphenyl, polyaromatic hydrocarbon and chlorinated benzene-laden materials to non-carcinogenic materials suitable for standard landfill disposal; volumetrically reducing shredded municipal solid waste; volumetrically reducing medical waste; volumetrically reducing existing rock formations of existing shale oil and reducing the shale oil to its constituents of hydrocarbon gas, oil and carbon; volumetrically reducing and desulfurizing bituminous coal to its constituents of at least hydrocarbon gas, oil, carbon and ash; and generating electricity (all claimed).    ADVANTAGE - The process: utilizes the argon, thus eliminating the possible formation of unwanted nitrogen-arene products; and produces high quality syngas and liquid fuels in a more economical and environmentally friendly manner.    DETAILED DESCRIPTION - Process (P1) for reducing an organic-containing material into lower molecular weight gaseous hydrocarbons, liquid hydrocarbons and solid carbon constituents, comprises: (a) feeding a sample of the organic-containing material into an infeed system that contains a non-flammable blanketing purge gas; (b) transferring the material into at least one microwave applicator containing the purge gas in a pressurized state above local atmospheric pressure; (c) exposing the material in the microwave applicator to at least two sources of microwaves from a bifurcated waveguide for a period of time sufficient to volumetrically reduce the material into the constituents, and a frequency of the microwaves of 894-1000 MHz and without an external heat source, where the microwaves are in non-parallel alignment to each other, so that one waveguide entry section to each applicator entry point is parallel to the flow of the organic material while the other is perpendicular to the flow of the organic material, and an impedance mismatch of the microwaves through the bifurcated waveguides results in circular polarization; (d) monitoring the microwaves so that any reflected microwave energy is redirected by a circulator and absorbed by a water load; (e) collecting gaseous byproduct constituents from the volumetrically reduced sample in the microwave applicator; (f) purging an outfeed system for the organic-containing material with the non-flammable blanketing purge gas; (g) removing the volumetrically reduced organic-containing material from the transporting means after passage from the outfeed system; and (h) cooling the collected gaseous byproduct constituents to allow condensables in the gaseous byproduct constituents to form a liquid. INDEPENDENT CLAIMS are also included for:    (1) an apparatus for reducing the organic-containing material into lower molecular weight gaseous hydrocarbons, liquid hydrocarbons and solid carbon constituents, comprising: at least one microwave generator (10); at least one sealed and purged microwave applicator purged with the non-flammable blanketing purge gas in proximity to a material to be reduced and in communication with the microwave generator via a pair of waveguides; a microwave energy absorber to absorb any reflected microwaves, where the absorber comprises a microwave monitor to detect reflected microwave energy, a circulator to redirect any reflected microwave energy, and a water load to absorb any reflected microwave energy, and the applicator receives only microwave energy; a transporting means with raised sides to transport the organic-containing material through the applicator; a purge gas generating means (11) to provide a purge gas to the microwave applicator during an initial purge cycle and over the organic material under reduction during operation, where the purge assembly system comprises an infeed purge assembly, and an outfeed purge assembly that are purged by the purge gas from the purge gas generating means; and a process gas cooling means to separate condensable and non-condensable hydrocarbon vapors, where the apparatus comprises no means capable of supplying external heat to the material to be reduced; and    (2) a process (P2) for generating electricity from reducing organic-containing materials into lower molecular weight gaseous hydrocarbons, liquid hydrocarbons and solid carbon constituents, comprising: the steps (a)-(c) as above per se, where a distance from the output from the bifurcated waveguide which couples the microwave energy to the applicator entry point parallel to the flow of the organic material is physically longer than the output feeding the perpendicular port; (d1) monitoring the microwaves; the steps (e)-(h) as above per se; and (i) feeding the collected gaseous byproduct constituents into a gas turbine.
