1. Viscosity and boiling point elevation of black liquor from the lignin extraction process and the modification of extracted lignin
Abstract : .... READ MORE

2. Towards a pure kraft lignin
Abstract : The most widely used production method for paper pulp in the world is kraft pulping. In chemical pulping the polymer, lignin, which binds the wood fibres together, is partly depolymerized. This allows the wood fibres to be separated from each other. READ MORE

3. Hydrothermal Liquefaction of Lignin into Bio-Oil
Abstract : Lignin, one of the three main components of lignocellulosic biomass, is the second most abundant organic polymer found on Earth. Nowadays, most of the lignin (almost 99%) produced in the Kraft pulping process is used as internal fuel. 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

5. Precipitation and separation of lignin from kraft black liquor
Abstract : The separation of lignin from black liquor is an attractive option to consider for pulp mills. In modern pulp mills, lignin extraction offers the opportunity of withdrawing an energy surplus in the form of a solid biofuel. READ MORE
