  1. 1. Modelling the chemical recycling of plastic waste via pyrolysis and analysing integration with existing refinery infrastructure

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Simon Dahl; [2023]
    Nyckelord :Pyrolysis; Recycling; Integration; Modelling; Simulation; Techno-economic; Plastic; Chemical engineering; Technology and Engineering;

    Sammanfattning : Current plastic management is unsustainable as large amounts of plastic end up landfilled or in the ocean, necessitating an expansion of waste management infrastructure. Pyrolysis is a viable chemical recycling option, and in this report a pyrolysis model is constructed in Aspen Plus. LÄS MER

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

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

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

    Sammanfattning : 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. LÄS MER

  4. 3. Thermal pretreatment of municipal solid waste

    Master-uppsats, Högskolan i Borås/Institutionen Ingenjörshögskolan

    Författare :Amir Badir; [2014]
    Nyckelord :Pyrolysis; Waste refinery; Pre-treatment of MSW; Thermal pretreatment Thermal gravimetric analysis TGA ;

    Sammanfattning : A kinetic study of the pyrolysis of municipal solid waste (MSW) was carried out bythermogravimetric analysis (TGA). Different runs were performed at heating rates of 5, 10and 150C/min. The effect of the N2, CO2 and O2 gas with different combination in theprocess was also evaluated. LÄS MER

  5. 4. Energy Modeling for an Eco-City with focus on Biogas Potential

    Kandidat-uppsats, KTH/Energiteknik

    Författare :Anton Julin; Johanna Siewert Delle; [2013]
    Nyckelord :;

    Sammanfattning : The Sino-Swedish Eco-City in Wuxi is the result of collaboration between the Chinese local government and several Swedish stakeholders aiming to create a sustainable urban infrastructure comprising environmentally conscious energy systems. The purpose of this report set forth is to investigate in how biogas production can be integrated into a possible energy system of this ecocity. LÄS MER
