Abstract:
A hydrogen storage composite formed article comprising a hydrogen storage material and a silicon-containing resin, the content of the silicon-containing resin being preferably 0.5 to 50 wt %; a method for preparing the formed article which comprises forming a hydrogen storage material by pressurizing, impregnating the resultant formed product with a solution comprising a solvent and a silicon-containing resin dissolved or dispersed therein, and curing the impregnated formed product; and a method for preparing the formed article which comprises admixing a hydrogen storage alloy with any one selected from among a silicon-containing resin, a solution of a silicon-containing resin and a dispersion of a silicon-containing resin, and then forming the resultant mixture followed by curing. The hydrogen storage composite formed article is free from pulverizing or collapse even after carrying out absorption and release repeatedly for a long period of time and excellent in heat resistance, formability and processability.
Abstract:
This disclosure provides a halogenated activated carbon composition comprising carbon, a halogenated compound and a salt. In some embodiments, the halogenated compound and the salt comprise a naturally occurring salt mixture, as may be obtained from ocean water, salt lake water, rock salt, salt brine wells, for example. In some embodiments, the naturally occurring salt mixture comprises Dead Sea salt.
Abstract:
Attrition resistant, sorbent compositions for the removal of elemental sulfur and sulfur compounds, such as hydrogen sulfide and organic sulfides, from cracked-gasoline and diesel fuels are prepared by the impregnation of a sorbent support comprising zinc oxide, expanded perlite, and alumina with a promoter such as nickel, nickel oxide or a precursor of nickel oxide followed by reduction of the valence of the promoter metal in the resulting promoter metal sorbent support composition.
Abstract:
A passive NO x adsorber is disclosed. The passive NO x adsorber is effective to adsorb NO x at or below a low temperature and release the adsorbed ΝΟχ at temperatures above the low temperature. The passive NO x adsorber comprises a noble metal and a molecular sieve having a MAZ Framework Type. The invention also includes an exhaust system comprising the passive NO x adsorber, and a method for treating exhaust gas from an internal combustion engine utilizing the passive NO x adsorber.
Abstract:
A biosorbent is provided which comprises algal based biomass coated with one or more metal cations, whereby the coated algal based biomass is capable of reducing or removing one or more oxyanions from water and/or another aqueous solution. Also provided is a method of using the biosorbent to at least partly remove one or more oxyanions from water and/or another aqueous solution, such as wastewater. In addition or alternatively, there is provided a method of removing metal cations from water and/or another aqueous solution, such as wastewater.
Abstract:
The present invention concerns a filtering medium, a method for the production thereof, the use of said filtering medium and a method for reducing the content of multiple contaminants simultaneously in fluids by means of said filtering medium, wherein said filtering medium consists of or comprises at least one of the following: a mixture (A) containing a major part of an iron-based powder and a minor part of a silver powder, an iron-silver powder alloy (B), and an iron-based porous and permeable composite containing silver (C).
Abstract:
Erfindungsgemäß wird ein Verfahren zur zumindest bereichsweisen Beschichtung eines Bauteils mit einer Schicht aus einem metallorganischen Netzwerk (MOF) bereitgestellt, bei dem der Körper mit einer Lösung enthaltend mindestens ein Metallsalz (MOF-Precursor), mindestens einen Linker und mindestens ein Lösungsmittel in Kontakt gebracht wird. Der Linker kann hierbei die Bindung der MOF-Schicht an die Oberfläche des Bauteils und/oder den Aufbau der MOF-Schicht vermitteln. Das Verfahren ist dadurch gekennzeichnet, dass die Lösung einen Temperaturgradienten aufweist, wobei die Temperatur der Lösung unmittelbar an der Oberfläche des Bauteils die Kristallisation einer MOF-Schicht auf der Oberfläche ermöglicht, während die Temperatur der restlichen Lösung die Bildung von MOF-Kristallen in der restlichen Lösung verhindert. Das Verfahren kann für die Herstellung von Bauteilen mit Schichten bestimmter chemischer und/oder physikalischer Eigenschaften verwendet werden. Darüberhinaus umfasst die Erfindung Bauteile, welche zumindest bereichsweise eine MOF-Schicht aufweisen. Eine mögliche Verwendungen besagter Bauteile findet sich in Sorptionskältemaschinen.
