  3. 2. Lignin Extraction from Black Liquor - Properties of the Liquors and Sulphur Content in the Lignin

    Författare :Ali Seid Moosavifar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat-treatment; lignin precipitation; boiling point elevation; lignin; alkalisation; biofuel; properties; viscosity; Black liquor; combustion of lignin; lignin modification; viscosity correlations.;

    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

  4. 3. Deepening the insights of lignin structure : Lignin-carbohydrate complex (LCC) fractionation and characterization and Kraft lignin amination

    Författare :Xueyu Du; Jiebing Li; Mikael Lindström; Jussi Sipilä; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    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

  5. 4. Thermochemical behavior of pretreated biomass

    Författare :Amit Kumar Biswas; Weihong Yang; Wlodzimierz Blasiak; Henrik Kusar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; Pretreatment; therochemical conversion; pyrolysis; combustion; SRA - Energy; SRA - Energi; Energy Engineering;

    Sammanfattning : Mankind has to provide a sustainable alternative to its energy related problems. Bioenergy is considered as one of the potential renewable energy resources and as a result bioenergy market is also expected to grow dramatically in future. However, logistic issues are of serious concern while considering biomass as an alternative to fossil fuel. LÄS MER

  7. 5. Phenolic Antioxidants in Wood Smoke

    Författare :Jennica Kjällstrand; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; smoke; benzene; methoxyphenols; antioxidants; wood; lignin; combustion; biomass;

    Sammanfattning : Smoke from residential wood burning constitutes a complex mixture of organic compounds with varying environmental and health effects. This thesis focuses on antioxidants and aromatic hydrocarbons emitted from small-scale burning. LÄS MER
