摘要： The invention is directed to an apparatus made of atmospheric-pressure microwave plasma torches for elimination of toxic airborne chemical and biological warfare agents. The apparatus can purify the interior air of large volume in an isolated space such as buildings, public transportation systems, and military vehicles contaminated with chemical and biological warfare agents. The apparatus consists of several microwave plasma torches connected in series for elimination and burnout of toxic airborne warfare agents. Microwave radiation generates an atmospheric plasma torch in certain conditions. Oxidation mechanism in the torch flames eliminates the chemical and biological warfare agents.

摘要： The present invention relates to an apparatus for heating a sample, such as chemical reaction mixtures, whose dielectric properties varies during the heating process. In particular, the present invention relates to a microwave heating apparatus comprising a microwave generator, a waveguide for guiding the generated microwaves to an applicator, and a deflector formed by a closed loop defining a plane, said deflector having an inherent resonance frequency and a thickness in a direction normal to said plane, the deflector being rotatable around an axis being at least substantially parallel to said plane, the deflector being positioned in the waveguide so as to form a resonant cavity with the sample and the waveguide applicator. The resonance conditions of the resonant cavity and the coupling factor of radiation from the waveguide to the cavity are easily adjustable by rotation of the deflector. The resonance conditions and the coupling factor can be adjusted in response to the dielectric properties of the sample in order to optimise the amount of absorbed power and thereby obtain control of the sample heating process.

摘要： A method for conversion of carbon dioxide to carbon monoxide comprises: introducing a flow of a dehumidified gaseous source of carbon dioxide into a reaction vessel; and irradiating dried, solid carbonaceous material in the reaction vessel with microwave energy. Heating of the irradiated carbonaceous material drives an endothermic reaction of carbon dioxide and carbon that produces carbon monoxide. At least a portion of heat required to maintain a temperature within the reaction vessel is supplied by the microwave energy. Carbon monoxide thus produced is allowed to flow out of the reaction vessel.

摘要： Conversion of heavy fossil hydrocarbons (HFH) to a variety of value-added chemicals and/or fuels can be enhanced using microwave (MW) and/or radio-frequency (RF) energy. Variations of reactants, process parameters, and reactor design can significantly influence the relative distribution of chemicals and fuels generated as the product. In one example, a system for flash microwave conversion of HFH includes a source concentrating microwave or RF energy in a reaction zone having a pressure greater than 0.9 atm, a continuous feed having HFH and a process gas passing through the reaction zone, a HFH-to-liquids catalyst contacting the HFH in at least the reaction zone, and dielectric discharges within the reaction zone. The HFH and the catalyst have a residence time in the reaction zone of less than 30 seconds. In some instances, a plasma can form in or near the reaction zone.
