NOVELTY - Reducing organic-containing material into lower molecular weight gaseous hydrocarbons, liquid hydrocarbons and solid carbon constituents, comprises: feeding a sample of organic-containing material into an infeed system; transferring the material into microwave applicator (12) containing non-flammable blanketing purge gas to insure that no air migrates into microwave applicator; exposing the material in microwave applicator to at least two sources of microwaves from at least a pair of divaricated waveguide assemblies (72); and collecting byproduct constituents from organic-containing material.    USE - The process is useful for reducing an organic-containing material into lower molecular weight gaseous hydrocarbons, liquid hydrocarbons and solid carbon constituents (claimed) including syngas, fuel oil or carbon.    ADVANTAGE - The process: is simple, more efficient and cost-effective, since it consumes less energy; and rapidly and safely dissociates hazardous organic materials (e.g. scrap tires, all types of scrap or discarded mixed plastics, discarded asphalt roofing shingles, municipal solid waste, organic compounds present in automotive shredder residue, poly chlorinated biphenyls, polycyclic aromatic hydrocarbons, and hexachlorobenzene compounds) into harmless byproducts with high quality, which can be directly introduced into an internal combustion gas turbine, in the petrochemical, industrial, and energy markets.    DETAILED DESCRIPTION - Reducing an organic-containing material into lower molecular weight gaseous hydrocarbons, liquid hydrocarbons and solid carbon constituents, comprises: feeding a sample of organic-containing material into an infeed system that contains a non-flammable blanketing purge gas; transferring the material into microwave applicator (12) containing the purge gas in a pressurized state above local atmospheric pressure to insure that no air migrates into microwave applicator which might cause a fire or explosion hazard; exposing the material in microwave applicator to at least two sources of microwaves from at least a pair of divaricated waveguide assemblies (72) for a period of time sufficient to volumetrically reduce the material into constituents, with a frequency of microwaves of 894-1000 MHz and without an external heat source, where the microwaves entering applicator are in non-parallel alignment to each other by using unequal lengths of waveguide (24) between sources of microwaves and applicator, the microwaves enter the applicator through applicator diffuser matrix for each divaricated waveguide, and matrix comprises four essentially parallel beveled entry channels; and collecting byproduct constituents from organic-containing material. An INDEPENDENT CLAIM is also included for an apparatus for reducing an organic-containing material into lower molecular weight gaseous hydrocarbons, liquid hydrocarbons and solid carbon constituents, comprising: at least one applicator chamber; at least two sources of microwaves; at least a pair of microwave waveguides of unequal length, where each waveguide is in communication with one of the sources of microwaves and the applicator chamber; and at least one applicator diffuser matrix at an entry port into the applicator chamber from each of the pair of microwave waveguides.
