  1. 6. Farm to furan derivatives : Fractionation of agricultural residues and transformation of sugars to chemical building blocks

    Författare :Sara Jonsdottir Glaser; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; sugar beet pulp; wheat bran; agricultural residue; biomass valorisation; fractionation; bio-based platform chemicals; HMF; levulinic acid; heterogeneous catalysis; whole-cell catalysis;

    Sammanfattning : The transition of industrial production from petrochemistry to a more sustainable economy requires the use of carbon neutral, renewable feedstock, which does not compete with food and feed supplies – by-products of farming and agro-food industry offer this possibility. With a limited range of low-value applications today coupled with the need for maximal utilisation of resources, the by-products of farming can be repurposed as feedstock for biorefineries. LÄS MER

  3. 7. Values Behind Welfare Technology and Their Possible Realization : Creation of a Technology Evaluation Method for Care Practices

    Författare :Annika Hasselblad; Leif Olsson; Katarina L Gidlund; Aron Larsson; Xiu Gu; Mittuniversitetet; []
    Nyckelord :Care; evaluation; technology; values; welfare technologies.;

    Sammanfattning : In 2018 the Swedish government approved a SEK 350 million grant to increase the municipal implementation and use of welfare technologies in areas such as health care, care, and social service. Welfare technologies have been criticized for their effects on care workers’ work environment, such as increased stress due to time and performance demands. LÄS MER

  4. 8. Entrained-Flow Gasification of Black Liquor and Pyrolysis Oil : Experimental and Equilibrium Modelling Studies of Catalytic Co-gasification

    Författare :Yawer Jafri; Rikard Gebart; Martin Seemann; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Black liquor; pyrolysis oil; catalytic gasification; co-gasification; gasification; entrained-flow gasification; pilot-scale; Energy Engineering; Energiteknik;

    Sammanfattning : The last couple of decades have seen entrained-flow gasification of black liquor (BL) undergo an incremental process of technical development as an alternative to combustion in a recovery boiler. The ability of the technology to combine chemical recovery with the production of clean syngas renders it a promising candidate for the transformation of chemical pulp mills into integrated forest biorefineries.
