Microwave chemical processing system having a microwave plasma reactor, and a multi-stage gas-solid separation system are disclosed. The microwave energy source has a waveguide, a reaction zone, and an inlet configured to receive the input material, and the input material is converted into separated components. The separated components include hydrogen gas and carbon particles. The multi-stage gas-solid separation system has a first cyclone separator to filter the carbon particles from the separated components, and a back-pulse filter system coupled to the output of the first cycle separator to filter the carbon particles from the output from the first cyclone separator.

A structural improvement for microwave-assisted high temperature high-pressure chemistry vessel systems is disclosed that among other advantages offers dynamic venting and resealing while a reaction proceeds and eliminates the risk of cross contamination associated with systems that use a common pressurized chamber. The improvement includes a relatively thin-walled disposable liner cylinder that includes one closed end and one open end defining a mouth, and a liner cap positioned in the mouth of the rigid liner cylinder for closing the rigid liner cylinder. The liner cap includes a depending column that engages the inside diameter of the rigid liner cylinder, and a disk at one end of the depending column having a diameter sufficient to rest upon the rigid liner cylinder without falling into the rigid cylinder liner so that the cylindrical liner cap can rest in the rigid liner cylinder at the mouth of the rigid liner cylinder. The depending column, includes a passage to provide a gas venting space, and a dynamic venting action, between the liner cap and the rigid liner cylinder.

A method and apparatus for controlling hydrogen gas storage in a clathrate hydrate structure through application of an electromagnetic field. The applied field can be used to control release of gas from the clathrate hydrate structure and/or uptake of gas into the clathrate hydrate structure. The electromagnetic field is arranged to promote hopping of gas molecules between and out of retaining pockets in the clathrate lattice by stimulating vibrations in the lattice that cause apertures into the retaining pockets to flex open. Advantageously, the electromagnetic field may have properties that are selected to promote an increase in the rate gas release or gas uptake without causing dissociation of the lattice. In this scenario, the invention can provide an energy-efficient, rechargeable on-demand supply system for any gas that can be retained within a clathrate hydrate structure.

The disclosure provides several pyrolysis reactor configurations and associated methods for generating pyrolysis products (e.g., oil, gas, and/or char) from organic feedstock.

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.

A system and method of forming a silicon-hybrid anode material. The silicon-hybrid anode material including a microparticle mixture of a quantity of silicon microparticles and a quantity of metal microparticles intermixed with the quantity of silicon microparticles in a selected ratio. The microparticle mixture is formed in a silicon-hybrid anode material layer having a thickness of between about 2 and about 15 m.

One object of the present disclosure is to provide a production method of magnesium hydride that is free of carbon dioxide and has high production efficiency, a power generation system that does not emit carbon dioxide or radiation using magnesium hydride, and an apparatus for producing magnesium hydride; therefore, the method for producing magnesium hydride of the present disclosure comprises a procedure for irradiating a magnesium compound different from magnesium hydride with hydrogen plasma, and a procedure for depositing a magnesium product containing magnesium hydride on a depositor for depositing magnesium hydride disposed within the range in which hydrogen plasma is present, wherein the surface temperature of the depositor is kept no more than a predetermined temperature at which magnesium hydride precipitates.

In order to suppress discharge of an unreacted content in a chemical reaction apparatus for irradiating a content with microwaves, a chemical reaction apparatus includes: a horizontal flow-type reactor in which a liquid content horizontally flows with an unfilled space being provided thereabove; a microwave generator that generates microwaves; and a waveguide that transmits the microwaves generated by the microwave generator to the unfilled space in the reactor, wherein the inside of the reactor is partitioned into multiple chambers to by overflow-type partition plates and that allow the content to flow thereover and an underflow-type partition plate that allows the content to flow thereunder.
