11. Oxidation of Kraft Pulp Fibres - Hydrogen Peroxide Oxidation under Acidic Conditions and its Influence on the Properties of Pulp
Sammanfattning : An increase in the use of bio-based products, combined with a decrease in the use of fossil-based products, is important for fulfilling the demands of a growing population in a sustainable manner. Moreover, reducing the usage of single-use plastics is vital in combating the plastic pollution that is afflicting our environment. LÄS MER
12. Precipitation of Kraft Lignin: Yield and Equilibrium
Sammanfattning : Kraft pulping is the dominant pulping process used in the world today. The material efficiency in modern kraft pulp mills is, however, only 40−55% and the final product consists mainly of cellulose. Recently, a novel process called “LignoBoost” has been introduced to separate lignin from kraft black liquor. LÄS MER
13. Aspects on Strenght Delivery and Higher Utilisation of the Strength Potential of Kraft Pulp Fibres
Sammanfattning : Studies on strength delivery and related fields have so far concentrated on finding the locations in the mill where fibres are damaged and what the damages consist of. However, fibres will invariably encounter mechanical stresses along the fibreline and in this thesis a new concept is introduced; the vulnerability of fibres to mechanical treatment. LÄS MER
14. Black Liquor Gasification-Based Biorefineries – Determining Factors for Economic Performance and CO2 Emission Balances
Sammanfattning : Biorefineries constitute an attractive future development option for the pulp and paper industry, allowing mills to produce not only pulp or paper but also other value-added products. Black liquor gasification (BLG) is currently being developed as an alternative technology for energy and chemical recovery in kraft pulp and paper mills. LÄS MER
15. Wood chips for kraft and sulfite pulping : evaluation of novel forest-industrial drum-chipping technology
Sammanfattning : Wood chipping and the supply of high-quality wood chips are of critical importance for most forest-industrial processes. The quality of wood chips affects product yield, product quality, and processability. LÄS MER
