  • Process for the hydrothermal treatment of high molar mass biomaterials
    Patent number: 10518245
    Abstract: The present invention concerns a process for the conversion of biomaterials into structural carbon products, particularly utilizing a hydrothermal treatment step that is carried out on a high molar mass organic starting material having a carbon content of >40 wt % of the dry matter. The invention also concerns a structural carbon product obtained using such a process, which has well-defined physico-chemical properties, e.g. in terms of surface area, carbon content, density, size and shape.
    Type: Grant
    Filed: December 18, 2013
    Date of Patent: December 31, 2019
    Assignee: Valmet Technologies Oy
    Inventors: Vidar Grönberg, Hanne Wikberg, Hans-Peter Hentze, Ali Harlin, Anna-Stiina Jääskeläinen

  • Thermostable xylanases
    Patent number: 6083733
    Abstract: The present invention discloses enzymes having xylanase activity. The xylanases are characterized in that they are active at a temperature of 80.degree. C. or higher. The enzymes are obtainable from anaerobic thermophilic bacteria. The enzymes are suited for use in paper and pulp production processes. The invention also describes cloning and expression of genes having xylanase activity obtained from the deposited strains.
