A method of producing an adsorption medium to remove at least one constituent from a feed stream. The method comprises dissolving at least one metal compound in a solvent to form a metal solution, dissolving polyacrylonitrile into the metal solution to form a PAN-metal solution, and depositing the PAN-metal solution into a quenching bath to produce the adsorption medium. The at least one constituent, such as arsenic, selenium, or antimony, is removed from the feed stream by passing the feed stre...

A cassette-based hydrogen fuel distribution and recovery method and system is disclosed.

An adsorbent for removal of impurities from silicone based solvents is presented. The adsorbent is regenerable for repeated use in cleaning silicone based solvents.

A zeolite catalyst is prepared by treating a zeolite with a phosphorus compound to form a phosphorus-treated zeolite. The phosphorus-treated zeolite is heated to a temperature of about 300.degree. C. or higher and combined with an inorganic oxide binder material to form a zeolite-binder mixture. The zeolite-binder mixture is heated to a temperature of about 400.degree. C. or higher to form a bound zeolite catalyst. The bound zeolite may exhibit at least two .sup.31P MAS NMR peaks with maxima at ...

An electro-kinetic air conditioner for removing particulate from the air creates an airflow using no moving parts. The conditioner includes an ion generator that has an electrode assembly including a first array of emitter electrodes, a second array of collector electrodes, and a high voltage generator. Preferably, a third or leading or focus electrode is located upstream of the first array of emitter electrodes, and/or a trailing electrode is located downstream of the second array of collector ...

A mod of combustion and a multi-component reactor to accomplish this mode of combustion are disclosed which produces fullerenes and fullerenic material by combustion. This mode consists of de-coupling an oxidation region of a flame from a post-flame region, thus giving greater control over operating parameters, such as equivalence ratio, temperature, and pressure; allows conditions of the operating parameters of the combustion reaction to be attained which would not be easily attained by convent...

The invention includes an ion affinity material having an organic component which is sulfonated and which is chemically bonded to an inorganic substrate component. The invention includes a method of forming a metal binding material. A solid support material comprising surface oxide groups is provided and an organic component having at least one alkyl halide is covalently linked to at least some of the surface oxide groups to form a modified support material. The at least one alkyl halide is subs...

A treatment apparatus for organic waste including a reaction vessel for introducing and decomposing organic waste and pulling out decomposed organic waste as a treated fluid. The reaction vessel includes an internal vessel made of corrosion-resistant material, an external vessel made of pressure-resistant material provided for surrounding the internal vessel via a gap, and an interconnection pipe for interconnecting the gap and the internal vessel outside the external vessel, thereby to control ...

This novel polymer-supported arene-ruthenium complex and catalyst thereof can be produced by a simple process, are stable and...

A process for regenerating a palladium catalyst from a catalytic reaction where the catalyst is contaminated with at least carbon. The regenerating is conducted prior to any heating step under oxidizing conditions in the regenerating section. The regenerating involves at least one heating step under a hydrogen-containing reducing atmosphere and under conditions sufficient to lower the content of carbon in the palladium catalyst.
