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

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

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

    Sammanfattning : 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. LÄS MER

  3. 2. Production, Purification, and Characterization of wood substrates and Galactose oxidase enzyme

    Master-uppsats, KTH/Industriell bioteknologi

    Författare :Rakhesh Pongalikonnar Ranganathan; [2023]
    Nyckelord :Peracetic acid treatment; Galactose oxidase; Pichia pastoris; Biomass recalcitrance; Enzymatic upgrading; Perättiksyrabehandling; Galaktosoxidas; Pichia pastoris; Motsträvighet i biomassa; Enzymatisk uppgradering;

    Sammanfattning : Trä är den bästa förnyelsebara källan för att producera många produkter på grund av dess biokompatibla och biologiskt nedbrytbara natur. Träets biomassa har en motstridig natur mot enzymatisk uppgradering. LÄS MER

  4. 3. Continuous Hydrothermal Co-liquefaction of Biomass : An experimental study on the effects of fuel mixing on the composition and yield of biocrude and hydrochar

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Simon Fridolfsson; [2022]
    Nyckelord :HTL; TGA; SEM EDS; Co-liquefaction effects; GROT; Kraft lignin; Microalgae;

    Sammanfattning : An experimental study on the effect of fuel mixing on the products resulting from hydrothermal liquefaction (HTL) was conducted. The feedstocks used were kraft lignin (KL), GROT (GT) and microalgae cultivated in wastewater (MA). Three sets of mixtures were prepared, each containing two types of feedstocks with a 1:1 ratio: KLGT, MAKL, and MAGT. LÄS MER

  5. 4. Sodium Model for Production Planning in a Paper Mill

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Isak Lindfors; [2022]
    Nyckelord :Paper Mill; Production Planning; Modelling; Liquor; Sodium;

    Sammanfattning : In today’s pulp and paper industry the Kraft process is the most common method for pulp production. This method uses sodium based chemicals (white liquor) in the cooking process to remove lignin from the wood chips and create pulp. LÄS MER

  7. 5. Sustainable Swedish Industry by Improved Excess Heat Recovery

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Erik Rosengren; [2022]
    Nyckelord :Excess Heat Recovery; Black Liquor Evaporation; Pulp and Paper; Retrofit; Agenda 2030; Water Technology; Resource Management; Waste Heat; Technical Validation; Chemical Engineering; Water Savings; Energy Efficiency; Greenhouse Gas mitigation; Spillvärme; Indunstning; Svartlut; Pappersmassaindustri; Energieffektivisering; Technology and Engineering;

    Sammanfattning : Achieving a sustainable Swedish industry will require better utilization of resources already available and already spent. Nationally, vast amounts of heat are released into the atmosphere and not made use of. LÄS MER
