4. Carbohydrate degradation and dissolution during Kraft cooking : Modelling of kinetic results
Sammanfattning : Chemical pulp fibres from wood are commonly used in products associated with packaging as well as with printing and writing. The prevalent way of liberating fibres is by subjecting wood chips to Kraft cooking. This process has a history of almost 130 years and should be both well described and well established. LÄS MER
5. Extraction of Lignin from Kraft Cooking Liquor by Ultrafiltration
Sammanfattning : Lignin is a potential biofuel which can be extracted from kraft cooking liquor. Lignin can also prove valuable as a speciality chemical. By extracting lignin potential economical revenue can be gained by pulp mills, as well as technical benefits such as easier delignification and bleaching. LÄS MER
