  1. 16. Negative Emission from Electric Arc Furnace using a Combination of Carbon capture and Bio-coal

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Abhijith Namboodiri Kapothanillath; [2023]
    Nyckelord :EAF; Off-gas handling; CCS; Calcium Looping CaL ; Post-combustion; Waste heat recovery; Bio-coal; Negative emissions; Techno-economic analysis; EAF; Avgasrening; CCS; Calcium Looping CaL ; Efterförbränning; Återvinning av spillvärme; Biokol; Negativa utsläpp; Teknisk-ekonomisk analys;

    Sammanfattning : Steel is one of the most essential metals in the world, and it plays a vital role in various industries. The growing demand for steel has resulted in increased CO2 emissions, with the steel industry contributing to approximately 7% of global emissions of carbon dioxide. LÄS MER

  3. 17. Ammonium and nitrate sorption by biochar

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Yasser Alrhban; [2023]
    Nyckelord :biochar nitrogen; retention; dialysis; absorption; adsorption; ammonium; nitrate;

    Sammanfattning : Biochar has recently drawn attention due to its ability to increase soil fertility, sequester carbon and its expected effect on reducing the leaching of elements from the soil, especially nitrogen. The possibility of using biochar as a soil amendment to reduce the amount of nitrogen leaching, and then reducing the quantities of nitrogen fertilizers used in agriculture to avoid the bad environmental effects has become a matter of great interest.

  4. 18. Biokol i foder till värphöns och slaktkycklingar

    Kandidat-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Viktor Mattsson; [2023]
    Nyckelord :biokol; foder; värphöns; ; kyckling; produktionsegenskaper;

    Sammanfattning : Inom produktionen av kyckling och ägg så är fodret den absolut största kostnaden. Ett bra foder är viktigt för att uppnå en bra produktion. Detta har medfört att lantbrukare och forskare har letat efter alternativa foderråvaror och tillsatser som kan bidra med positiva effekter på djuren för att få en högre produktion. LÄS MER

  5. 19. Developing an Environmentally Friendly Approach for Ash Removal in Hard Carbon Anodes

    Master-uppsats, KTH/Materialvetenskap

    Författare :Diwen Wang; [2023]
    Nyckelord :Hard carbon; Acid wash; Biochar; Sodium-ion battery; Hårt kol; Syratvätt; Biokol; Natriumjonbatteri;

    Sammanfattning : Hard carbon is regarded as one of the most promising anode materials for sodium-ion battery. However, the ash content of the hard carbon anode inherited from the precursor have several negative impacts on the electrochemical performance of hard carbon. LÄS MER

  7. 20. Techno-economic analysis of a waste-to-energy system using innovative pyrolysis process

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Hannah Sofie Perrens; [2023]
    Nyckelord :Waste management; pyrolysis; heat and power generation; decentralized energy systems; waste-to-energy;

    Sammanfattning : Waste management is of growing concern with increasing amount of municipal waste generation and the industry standards are becoming stricter due to climate goals and sustainable development. Waste-to-energy (WTE) systems in the form of waste incineration have been promoted as a low-carbon energy source, but nevertheless have high greenhouse gas (GHG) emissions. LÄS MER
