2. Equilibrium of lignin precipitation: The effects of pH, temperature, ion strength and wood origins
Abstract : The kraft process is the predominant method for producing pulp in Scandinavia. However, the material efficiency in modern kraft pulp mills for pulp production is only 40−55% and the final product consists mainly of cellulose. A novel process called “LignoBoost” has been introduced recently for extracting lignin from alkaline black liquor. READ MORE

3. Synthesis and analysis of carbohydrates related to bacterial polysaccharides
Abstract : The outer surface of bacteria is composed of around 75% carbohydrates, which are vital for the bacteria to survive and communicate with the host biological system. The thesis discusses different properties of carbohydrates that are essential for understanding the bacterial behavior in biological systems. READ MORE

4. Precipitation of Kraft Lignin: Yield and Equilibrium
Abstract : 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. READ MORE
