1. Viscosity and boiling point elevation of black liquor from the lignin extraction process and the modification of extracted lignin
Sammanfattning : .... LÄS MER
2. Lignin Extraction from Black Liquor - Properties of the Liquors and Sulphur Content in the Lignin
Sammanfattning : Kraft lignin isolated by precipitation can be considered as being a valuable renewable source of energy and material. Removing lignin from black liquor is also advantageous as it decreases the load on the recovery boiler, which is usually the limiting factor in the production of kraft pulp. LÄS MER
3. Biosynthesis, interactions, and structure of native lignin
Sammanfattning : Wood biomass is an important resource in the development ofstrategies towards replacement of fossil-based materials. Woodcomprises cellulose, hemicelluloses and lignin, in amounts thatvary between species. LÄS MER
4. Nonionic surfactants from kraft lignin
Sammanfattning : .... LÄS MER
5. Deepening the insights of lignin structure : Lignin-carbohydrate complex (LCC) fractionation and characterization and Kraft lignin amination
Sammanfattning : Improvement of kraft pulping delignification efficiency and value-addition of industrial kraft lignin are two attractive topics. The proposal that delignification is deteriorated by the presence of lignin-carbohydrate complex (LCC) is still being debated. LÄS MER
