  1. 11. Energy and material recovery from high-ash waste through pyrolysis

    Författare :Katarzyna Jagodzińska; Weihong Yang; Pär Jönsson; Tobias Richards; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pyrolysis; torrefaction; landfill waste; shredder fines; hydrogen production; carbon nanotubes; circular economy; pyrolys; torrefiering; avfall från deponier; finfraktioner från fragmentering; vätgasproduktion; kolbaserade nanorör; cirkulär ekonomi; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : Undoubtedly, the past practices of profit maximisation by all means, which fuelled swift industrialisation and urbanisation, left behind a legacy of non-sanitary old landfills polluting the environment. These, together with active landfills supplied with tremendous streams of waste produced annually, are a loose cannon calling for action. LÄS MER

  3. 12. A framework for supply chain configuration for a biomass-to-energy pre-treatment process

    Författare :Martin Svanberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : A transition from fossil fuel to renewable energy sources such as biomass is an environmentally sustainable pathway. However, increased use of biomass is hampered by a number of barriers regarding movement of energy: through place, through time and through existing energy infrastructure. LÄS MER

  4. 13. Thermochemical behavior of pretreated biomass

    Författare :Amit Kumar Biswas; Weihong Yang; Wlodzimierz Blasiak; Henrik Kusar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; Pretreatment; therochemical conversion; pyrolysis; combustion; SRA - Energy; SRA - Energi; Energy Engineering;

    Sammanfattning : Mankind has to provide a sustainable alternative to its energy related problems. Bioenergy is considered as one of the potential renewable energy resources and as a result bioenergy market is also expected to grow dramatically in future. However, logistic issues are of serious concern while considering biomass as an alternative to fossil fuel. LÄS MER

  5. 14. From Combined Heat and Power to Polygeneration

    Författare :Fredrik Starfelt; Jinyue Yan; Eva Thorin; Umberto Desideri; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : In order to reach targets on reducing greenhouse gas emissions from fossil resources it is necessary to reduce energy losses in production processes. In polygeneration, several processes are combined to complement each other to avoid sub-optimization of the standalone processes. LÄS MER

  7. 15. Characterization and densification of carbonized lignocellulosic biomass

    Författare :Magnus Rudolfsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis focuses on developing two main areas: characterization and densification of carbonized lignocellulosic biomass. Thermally treated biomass undergoes changes that enrich the content of carbon in the remaining solid fraction. LÄS MER
