  1. 6. 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

  3. 7. 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

  4. 8. Assessment of promoter regulation in Pseudomonas putida using GFP and flow cytometry

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Luka Cululejevic; [2022]
    Nyckelord :applied microbiology; Pseudomonas putida; promoter characterization; aromatic compounds; vanillin; guaiacol; Biology and Life Sciences;

    Sammanfattning : Lignin is found in all biomass and is an abundant natural source of aromatic compounds. It has the potential to serve as a renewable raw material for a variety of chemicals currently derived from fossil fuel sources such as muconic acid, an important platform chemical. Kraft lignin is a waste stream from the pulp and paper industry. LÄS MER

  5. 9. 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

  7. 10. Thermally insulating carbon foams from carbonized kraft lignin

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Isabelle Hernodh Svantesson; [2021]
    Nyckelord :Carbon foams; thermal insulation; kraft lignin; carbonization; thermal conductivity; Kolskum; värmeisolering; kraftlignin; karbonisering; värmeledningsförmåga;

    Sammanfattning : Kolmaterial, såsom kolfibrer och kolskum, används som värmeisolatorer i applikationer vid höga temperaturer. För närvarande härleds dessa material från fossilbaserade källor, vilket tyder på ett behov av att hitta alternativa kandidater baserade på förnybara källor. LÄS MER
