  • Patent number: 10279328
    Abstract: The invention is directed to the production of metal-carbon containing bodies, which process comprises impregnating cellulose, cellulose-like or carbohydrate bodies with an aqueous solution of at least one metal compound, followed by heating the impregnated bodies in an inert and substantially oxygen-free atmosphere, thereby reducing at least part of the at least one metal compound to the corresponding metal or metal alloy.
    Type: Grant
    Filed: November 19, 2014
    Date of Patent: May 7, 2019
    Assignee: BASF Corporation
    Inventors: Jacobus Hoekstra, John Wilhelm Geus, Leonardus Wijnand Jenneskens, Dirk van de Kleut, Edward Jan Vlietstra
  • Patent number: 9174205
    Abstract: The invention is directed to a method for preparing catalytically active activated carbon, to catalytically active activate carbon obtainable by the method, and to the use of the catalytically active activated carbon. The method of the invention method comprises the steps of: i) mixing charcoal with one or more organic nitrogen-containing compounds, said nitrogen-containing compounds comprising, next to a first nitrogen atom, at least two or more further heteroatoms selected from the group consisting of nitrogen and oxygen, wherein said further heteroatoms have a lone pair; ii) drying the mixture obtained in step i); iii) activating the dried mixture using steam, thereby producing catalytically active activated carbon.

  • Patent number: 6866699
    Abstract: The invention is directed to a process for the adsorption of organic vapours from gas mixtures containing them onto activated carbon, where the process comprises passing the gas mixture consecutively through at least a first and a second adsorption system, the first system consisting of activated carbon having a first adsorption rate for the organic vapours and the second system consisting of an adsorbent having a second adsorption rate for the organic vapours, the second adsorption rate being higher than the first adsorption rate, more in particular to such process when used in the operation of vehicle internal combustion engines.
