1. Equilibrium of lignin precipitation: The effects of pH, temperature, ion strength and wood origins
Sammanfattning : 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. LÄS MER
2. 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
