Abstract: The invention described herein generally pertains to a process for reducing an organic-containing material into lower molecular weight gaseous hydrocarbons, liquid hydrocarbons and solid carbon constituents, said process including the steps of: feeding a sample of said organic-containing material into an infeed system, wherein the infeed system contains a non-flammable blanketing purge gas; transferring the material into at least one microwave applicator containing the purge gas in a pressurized state above local atmospheric pressure to insure that no air migrates into said microwave applicator which might cause a fire or explosion hazard; exposing the material in said microwave applicator to at least two sources of microwaves from at least a pair of divaricated waveguide assemblies for a period of time sufficient to volumetrically reduce said material into said constituents, a frequency of said microwaves between approximately 894 MHz and approximately 1000 MHz and without an external heat source, the microw

Abstract: The invention described herein generally pertains to coupling microwave energy into a tuned multi-section WR-975 waveguide assembly, connected to a waveguide containing a ceramic cylindrical applicator, terminated in a dummy load, for pre-heating fuels to improve vaporization, combustion efficiency, and soot reduction in combustion chamber(s). Designed primarily for processing liquid byproducts produced during biodiesel fuel manufacturing, this invention establishes a charge density in a cross-coupled applicator, according to the applicator's volume, dielectric characteristics of the materials being processed, applied frequency, and voltage. This invention may also be used for preheating or polarization of solids within a pipe-conveyed slurry, such as biosolids, bituminous coal, crude oil sludge, paper pulp or shale oil rock.

Abstract: The invention described herein generally pertains to utilization of high power density microwave energy to reduce organic compounds to carbon and their constituents, primarily in a gaseous state. The process includes, but is not limited to, scrap tires, plastics, asphalt roofing shingles, computer waste, medical waste, municipal solid waste, construction waste, shale oil, and PCB/PAH/HCB-laden materials. The process includes the steps of feeding organic material into a microwave applicator and exposing the material to microwave energy fed from at least two linear polarized sources in non-parallel alignment to each other, and collecting the material. The at least two sources of microwave energy are from a bifurcated waveguide assembly, whose outputs are perpendicular to each other and fed through waveguide of proper impedance, such that the microwave sources are physically and electrically 90° out of phase to each other. The microwave frequency is between 894 and 1000 MHz, preferably approximately 915 MHz.

Abstract: The invention described herein pertain generally to a process for drying and/or pathogen reduction as well as an apparatus effective for the same, the process comprising the steps of feeding a sample containing water onto a mesh conveyor belt; transporting the sample into a heated chamber having an air flow about, around and through the sample; exposing said sample to at least two sources of microwaves in non-parallel alignment to each other; and collecting the sample. The at least two sources of microwaves are from a split waveguide assembly, producing microwaves which are essentially 90° out of phase to each other. The heated chamber is between approximately 75° C. and 125° C. The convection heating supplements the microwave heating thereby both heating the sample from the outside in and also from the inside out. The microwave frequency is between 915 MHz and 1000 MHz, preferably approximately 915 MHz.
