  2. 1. Hardwood delignification

    Author : Linus Kron; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Precipitated lignin; Black liquor; Hardwood; Kraft delignification; Mass transport;

    Abstract : For the necessary transition into a sustainable and circular society, lignocellulosic resources are set to play a crucial role in replacing fossil-based materials. In the valorisation of lignocellulosic materials, kraft pulping is one of the key processes. READ MORE

  4. 2. Fractionation of hardwood using steam explosion and hydrotropic extraction : Process development for improved fractionation

    Author : Johanna Olsson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrotropic fractionation; ; Steam explosion; hardwood; sodium xylene sulphonate; Lignocellulosic Biomass; Hydrotropic extraction; Steam explosion; Hardwood; Sodium xylene sulphonate; Lignocellulosic biomass;

    Abstract : The utilisation of biomass instead of fossil resources is an important alternative for the transition into a sustainable society. Biomass, owing to its primary constituents—cellulose, hemicelluloses and lignin—has the potential to replace many products that are produced from fossil resources today, including plastics, textile fibres and fuels.

  7. 5. SAWING STRATEGIES FOR TROPICAL HARDWOOD SPECIES : Simulation studies based on industrial conditions of Mozambique

    Author : Pedro Ah Shenga; Dick Sandberg; Olof Broman; Mats Nylinder; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sawing strategies; tropical hardwood species; simulation; volume yield; log grading; umbila; jambirre; Träteknik; Wood Science and Engineering;

    Abstract : The harvesting of Mozambique tropical hardwood species is considerable higher than the natural regrowth in the forest and the stock is decreasing drastically. Therefore, it is important to improve the material recovery when the wood is refined (i.e., in sawing and further refinement to products such as joineries, furniture etc. READ MORE
