  5. 39. Selective Separation Of Wood Components In Internal Process Waters Originating From Mechanical Pulping

    Författare :Dariusz Zasadowski; Magnus Norgren; Bjarne Holmbom; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; flotation; foaming agents; chelating surfactant; TMP process water; pitch control; internal cleaning stage; hemicellulose recovery; anti‐solvents; solvents; precipitation;

    Sammanfattning : Dissolved and Colloidal substances (DSC) and metals are released from woodduring thermomechanical pulp (TMP) production. These components have atendency to accumulate in process waters, as the water circulation systems inintegrated paper mills are closed. LÄS MER

  7. 40. On the physico-chemical properties of softwood hemicellulose and compounds derived from it

    Författare :Polina Naidjonoka; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Hemicellulose is the second largest polysaccharide group available in nature after cellulose. Hemicellulose is present in plant cell walls along with cellulose and lignin. It is an abundant and biodegradable material that could potentially replace fossil-based products. LÄS MER
