Systems and methods for synthesizing nanocrystals using continuous, microwave-assisted, segmented flow reactor.

A process and catalyst for the in situ generation of hydrogen via the microwave irradiation of a ruthenium chitosan composite catalyst has enabled the convenient reduction of nitro compounds in aqueous medium.

A contaminated medium (such as soil and/or groundwater) contaminated with petrogenic and/or other organic contaminants such as petroleum hydrocarbons, light non- aqueous phase liquids (NAPLs), dense non-aqueous phase liquids (DNAPLs), persistent organic pollutants (i.e. sulfolane), chlorinated compounds, and volatile organic compounds, can be mixed with enhanced stimulators and be thermally remediated. The enhanced stimulators are heat induced to undergo exothermic reactions, which initiate a series of in-situ chemical reactions to such as to produce hydrogen gas. The hydrogen gas causes hydrocracking of heavy hydrocarbons to produce light hydrocarbons which can be recovered such as for future use.

Apparatus and method for plasma synthesis of carbon nanotubes couple a plasma nozzle to a reaction tube/chamber. A process gas comprising a carbon-containing species is supplied to the plasma nozzle. Radio frequency radiation is supplied to the process gas within the plasma nozzle, so as to sustain a plasma within the nozzle in use, and thereby cause cracking of the carbon-containing species. The plasma nozzle is arranged such that an afterglow of the plasma extends into the reaction tube/chamber. The cracked carbon-containing species also pass into the reaction tube/chamber. The cracked carbon-containing species recombine within the afterglow, so as to form carbon nanotubes in the presence of a catalyst.

A process and an apparatus for converting carbon dioxide CO.sub.2 into carbon monoxide CO using hydrocarbons are described. In further embodiments, processes and apparatuses for generating synthesis gas and processes and apparatuses for converting synthesis gas into synthetic functionalised and/or non-functionalised hydrocarbons using CO.sub.2 and hydrocarbons are described. The processes and apparatuses are adapted to convert CO.sub.2 emitted by industrial processes, and thus the amount of carbon dioxide emitted into the atmosphere may be reduced.

A microwave irradiating and heating device including: a reaction furnace containing a sample material to be irradiated with a microwave passed through an opening and to be heated; a microwave irradiating source disposed outside the reaction furnace; a rotated quadric surface mirror reflecting microwave emitted from the microwave irradiating source toward the opening, and disposed above the reaction furnace; a lid for the opening, at least a portion of the lid made from dielectric to transmit microwave reflected on the rotated quadric surface mirror into the reaction furnace; wherein an angle of incidence of the microwave, reflected on the rotated quadric surface mirror and irradiated at the portion of the lid made from the dielectric, is at an angle causing a polarized wave of the microwave to pass through the portion.

In order to provide a microwave treatment apparatus capable of properly controlling microwave irradiation, a microwave treatment apparatus 1 includes: an irradiating portion that performs microwave irradiation from multiple emitting portions; a moving portion that individually moves the multiple emitting portions; and a control portion that controls movements of the emitting portions by the moving portion, wherein the irradiating portion is such that phases of microwaves that are emitted from the multiple emitting portions are changeable, and the control portion controls phases of microwaves that are emitted by the irradiating portion from the multiple emitting portions.

Removing GHGs from various industrial and agricultural sources while concurrently generating useful solid and/or gaseous output materials enables an environmentally-clean and scalable approach for permanently dissociating the GHGs. Intra-reactor conditions can be controlled such that the solids produced are useful in advanced materials (e.g., in carbon fibers, in cements and concretes, etc.), and/or controlled in a manner such that the generated gases are useful (e.g., as fuel in hydrogen powered vehicles, in aeronautical and aerospace applications, and in energy storage applications, etc.). Eradicating GHGs (i.e., by dissociating GHGs into constituent carbon, hydrogen, oxygen, sulfur, nitrogen, etc.) is facilitated through use of interconnected arc discharge reactors. Arc discharge reactors involve simple designs that are both energy efficient and highly scalable to virtually any specification. Moreover, the simplicity of arc discharge reactor designs lead to large scale configurations that can be reliably deployed into diverse geographies or environments having diverse operating conditions.

An apparatus for producing ammonia using electric discharge of water according to an embodiment of the present invention includes a plasma decomposition reaction part configured to produce hydrogen (H.sub.2) and oxygen (O.sub.2) from water by supplying the water to plasma generated by using nitrogen gas (N.sub.2) as electric discharge gas and produce nitrogen monoxide (NO) and nitrogen dioxide (NO.sub.2) by allowing oxygen (O.sub.2) to react with nitrogen (N.sub.2), a thermal decomposition reaction part connected to a lower side of the plasma decomposition reaction part and configured to produce solid carbon and hydrogen (H.sub.2) by decomposing water and hydrocarbon by further supplying hydrocarbon or hydrogen to an additional supply port, and a synthetic catalyst part connected to the thermal decomposition reaction part and configured to produce ammonia (NH.sub.3) by synthesizing hydrogen (H.sub.2) and nitrogen monoxide (NO) separated from water.

A livestock food product that includes at least one or more plant-based agricultural feeds containing at least one or more plant residues of at least one or more noxious and/or invasive plants. The one or more residues containing no more than 10% of the naturally occurring amount, by weight, of at least one noxious compound that was present in the one or more noxious and/or invasive plants, the naturally occurring amount being the amount of the at least one noxious compound that was present in the noxious and/or original plants while they were alive. The one or more noxious and/or invasive plants including at least one of hemp, tumbleweed, sagebrush, or cheat grass. These plants fibers contain valuable nutrients and flourish under semiarid conditions in abundance. Proper harvesting techniques, bioprocessing can make these plant valuable resources available to mankind environmentally and economically.
