  1. 1. Recovery of Dialcohol Cellulose using Micro- and Ultrafiltration Processes

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Lina Näslund; Gabriella Petersson; [2023]
    Keywords : Membrane filtration; Ultrafiltration; Microfiltration; Dialcohol cellulose; DAC; Bioplastics; Chemical engineering; Process design; Technology and Engineering;

    Abstract : The waste management and production of plastic play a concerning part in global warming and continues to have a negative effect on the environment. A promising strategy to address this challenge is to develop new sustainable materials, to replace current fossil-based plastics. READ MORE

  3. 2. Fractionation of Wheat Bran for Utilisation in Biorefinery

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Gabriella Haag; [2021]
    Keywords : Wheat bran; biorefinery; chemical engineering; vetekli; bioraffinaderi; extraction; Technology and Engineering;

    Abstract : Wheat bran is a by-product from the production of wheat flour. Nowadays wheat bran is mostly used as feed for animals, in the food and baking industry or it is simply burned in open air. READ MORE

  4. 3. Microwave Heat Treatment of Black Liquor for the Degradation of Hemicellulose

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Maja Rydgård; [2020]
    Keywords : lignin; biofuel; black liquor; heat treatment; microwave heating; chemical engineering; kemiteknik; Technology and Engineering; Chemistry;

    Abstract : The largest use of fossil petroleum is the production of fuels. Hence, finding sustainable alter-natives is an important step to reduce the emissions of greenhouse gases. One such alternative is to produce fuel from biomass, such as waste products from agriculture and the forest indus-try. READ MORE

  5. 4. Biocarbon production from biomass based energy plant forapplication in high-value materials

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : David Söderberg; [2019]
    Keywords : ;

    Abstract : Natural graphite, a type of carbon, is used in most battery driven electronic devices around the world as it serves as the anode in Li-ion batteries. Since 67\% of global production of graphite originates from a single country the EU has classified it as a critical raw material with a high supply risk. READ MORE

  6. 5. Intensification of lignocellulosic bioethanol production process using multi-staged membrane bioreactors

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Clarisse Uwinez; [2019]
    Keywords : Interconnected continuous hydrolysis and fermentation; lignocellulosic bioethanol; Membrane bioreactors; process intensification; lignin recovery; membrane fouling.;

    Abstract : The exploitation of lignocellulosic materials with the aim of producing high value-added products will potentially counteract concerns related to the depletion of fossil resources or exponential population growth. Bioethanol produced from lignocellulosic agriculture residue exhibits promising alternative to the petroleum-based fossil fuel which reduces net emission of greenhouse gases (GHG). READ MORE
