  • Process for Producing Carbon Blacks With Reduced Polycyclic Aromatic Hydrocarbon Content Utilizing Supercritical Fluid Extraction
    Publication number: 20240043693
    Abstract: Provided is a process for producing a purified carbon black with a reduced content of polycyclic aromatic hydrocarbons. The process includes (a) providing a carbon black including an initial content of polycyclic aromatic hydrocarbons, (b) treating the carbon black including an initial content of polycyclic aromatic hydrocarbons with an extraction agent including carbon dioxide in a supercritical state to extract at least a portion of the polycyclic aromatic hydrocarbons from the carbon black, and (c) removing the extraction agent including the extracted polycyclic aromatic hydrocarbons from the carbon black to obtain a purified carbon black with a lower content of polycyclic aromatic hydrocarbons than the initial content of polycyclic aromatic hydrocarbons. It is furthermore provided a carbon black obtained through said production process and articles made therefrom.

  • Catalyst system based on spherical activated carbon as a carrier and use thereof
    Patent number: 9975109
    Abstract: The invention relates to a method for producing a catalyst system having at least one catalytically active component, wherein the catalytically active component comprises at least one metal, wherein first a spherical activated carbon used as a catalyst carrier is subjected to an oxidation. Subsequently, the catalytically active component is applied, optionally followed by a reduction of the catalyst system obtained in said manner.

  • Porous heterogeneous catalyst coated with an ionic liquid
    Patent number: 8334232
    Abstract: The invention relates to a porous heterogeneous catalyst. In order to prepare a catalyst which catalyzes with a relatively high selectivity the hydrogenation of individual unsaturated bonds of polyunsaturated compounds it is proposed that the inner surface of the catalysts is coated with an ionic liquid.
