  • Patent number: 12285844
    Abstract: A method of abrading the surface of a workpiece is disclosed. The method includes providing a workpiece, an abrading apparatus with a backing pad configured to receive an abrading plate, an abrading plate attachable to the backing pad and a slurry including abrasive grains; attaching the abrading plate to the backing pad; providing the slurry including abrasive grains between the abrading plate and the surface of the workpiece; and operating the abrading apparatus to abrade the surface of the workpiece. Therein, the abrading plate includes a workpiece-facing layer, which workpiece-facing layer faces the surface of the workpiece and includes a metal or a polymer, and the abrasive grains have a hardness on the Mohs scale of greater than 5.

  • Patent number: 8282705
    Abstract: A method is provided for recovering metals from a spent catalyst composition containing an organic contaminant and catalytically active metals on a catalyst support. The metals are leached from the spent catalyst composition by adding under stirring an ionic liquid. The ionic liquid containing the leached metals is separated from the organic contaminant and the catalyst support by adding under stirring an anti-solvent. After removing the organic contaminant and the catalyst support, the leached metals are separated from the ionic liquid for example by selective precipitation, ion exchange, solvent extraction, electrodeposition, chromatographic, or pyrometallurgical methods.

  • Patent number: 7014898
    Abstract: A fibrous catalyst comprises at least one transition metal anchored to a polymer fiber having a plurality of grafted units grafted to a polymer backbone. The polymer backbone may be a polyolefin, a fluorinated polyethylene, cellulose or viscose. The grafted units comprise a salt of a carboxylic acid, which in a preferred embodiment is a sodium salt of acrylic acid. The catalysts are particularly suitable for scavenging oxygen from sealed packages or containers and may further comprise a chemical indicator for the presence or absence of oxygen.
