  • Patent number: 8110519
    Abstract: The objective is to present compositions obtained by supporting by polymers micro clusters of transition metals and the like that are useful as catalysts in various reactions and, once used, are readily recovered and reused. A polymer-supported metal cluster composition is obtained by supporting a transition metal by a cross-linked polymer, and the polymer-supported cluster composition is characterized by the cross-linked polymer obtained by cross-linking of a cross-linkable polymer containing a hydrophilic side chain and a hydrophobic side chain group having a cross-linkable functional group. This polymer-supported metal cluster composition is, for example, preferably formed by first forming a micelle composed of the metal clusters supported by the cross-linkable polymer in a suitable solution and subsequently subjecting the cross-linkable polymer to a cross-linking reaction.

  • Patent number: 8101304
    Abstract: The present invention relates to a process for the concentration of noble metals from fluorine-containing components of fuel cells, for example from PEM fuel cell stacks, DMFC fuel cells, catalyst-coated membranes (CCMs), membrane electrode assemblies (MEAs), catalyst pastes, etc. The process is based on an optionally multi-step heat treatment process comprising a combustion and/or a melting process. It allows an inexpensive, simple concentration of noble materials. The hydrogen fluoride formed during the heat treatment of fluorine-containing components is bound by an inorganic additive so that no harmful hydrogen fluoride emissions occur. The process can be used for the recovery of noble metals that are present as components in fuel cells, electrolysis cells, batteries, and the like.

  • Publication number: 20110119993
    Abstract: The present invention relates to the processing of hydrocarbon-containing feedstreams in the presence of an interstitial metal hydride containing catalyst and hydrogen at process conditions of at least 400 psig pressure and temperatures of at least 200° C. These processes use interstitial metal hydrides that possess significant hydrogen capacities and high hydrogen kinetics rate properties. The catalysts and processes of the present invention may be used with or without radio frequency or microwave energy and are preferably run under conditions of high hydrogen partial pressure above about 350 psia. The catalysts and processes of the present invention can improve overall hydrogenation, product conversion, as well as sulfur reduction in hydrocarbon feedstreams as compared to processes of the prior art operated under similar conditions.

  • Publication number: 20110092361
    Abstract: Methods for improving the sulfur-tolerance of nickel-based catalyst systems, as well as the improved catalyst systems, are disclosed. The methods can include adding praseodymium alone, or in combination with ruthenium and/or cerium, to a nickel-based catalyst system, thereby inhibiting sulfur poisoning of the catalyst system. Improved catalyst systems can have an added amount of praseodymium alone, or in combination with ruthenium and/or cerium, sufficient to inhibit poisoning of the system by sulfur.

  • Patent number: 7928049
    Abstract: The present invention relates to the use of metal complex compounds having hydrazide ligands as oxidation catalysts. Further aspects of the invention are formulations comprising such metal complex compounds, novel metal complex compounds and novel ligands. The metal complex compounds are used especially for enhancing the action of peroxides, for example in the treatment of textile material, without at the same time causing any appreciable damage to fibers and dyeings. There is also no appreciable damage to fibers and dyeings if these metal complexes are used in combination with an enzyme or a mixture of enzymes.

  • Publication number: 20110076225
    Abstract: A hydrogen generator capable of operating in any orientation and having no moving parts includes a catalyst retaining structure. The catalyst retaining structure is disposed in a housing and serves to separate the housing into a fuel holding portion and a hydrogen chamber. The catalyst retaining structure also includes one or more pores, each pore being in communication with the fuel holding and hydrogen chambers. A catalyst, that promotes the generation of hydrogen gas upon contact with the fuel, is disposed within the pores. The fuel enters the pores and thereupon generates hydrogen gas which passes into the hydrogen chamber. Contact of the fuel with the catalyst in the pores may be controlled and the position of the fuel-hydrogen interface within the pore may be moved so as to regulate the generation of hydrogen. The catalyst retaining structure can take different forms, including one or more hollow elongated members or plates, and may further incorporate hydrophobic and/or hydrophilic membranes.
