  1. 11. Practical implementation of Bio-CCS in Uppsala : A techno-economic assessment

    University essay from KTH/Energiteknik

    Author : Robert Djurberg; [2020]
    Keywords : BECCS; Bio-CCS; CCS; techno-economic assessment; BECCS; Bio-CCS; CCS; teknoekonomisk analys;

    Abstract : To decrease global warming, bioenergy with carbon capture and storage (Bio-CCS) has been proposed as an effective and necessary tool. Combusting biomass and capturing carbon dioxide (CO2) from the same process results in net negative emissions, hence, reducing the concentration of CO2 in the atmosphere. READ MORE

    University essay from KTH/Materialvetenskap

    Author : Alice Moya; [2019]
    Keywords : high temperature corrosion; austenitic steel; cast iron; cast steel; oxidation; exhaust gas; engine; heavy-duty trucks;

    Abstract : Increasing awareness of environmental protection has made both governments and the industry aim for lowering carbon dioxide emissions. For the transport industry this means increasing engine efficiency, replacing fossil fuels with bio-based fuels or full electrification. READ MORE

  4. 13. A Life Cycle Assessment of the Environmental Impacts of Cross-Laminated Timber

    University essay from Lunds universitet/Byggproduktion

    Author : Emma Svensson; David Panojevic; [2019]

    Abstract : Consumers demand healthy food with less residues of pesticides, in addition to the global awareness of the negative impact such chemicals have caused to the environment during the last decades. Farmers and other agricultural participants are far away from completely end up the usage of pesticides but currently used practice could stepwise be improved in pest management. READ MORE

  6. 15. Modelling of Biomass Pyrolysis with Ex-situ Catalytic Upgrading for Bio-crude Production

    University essay from KTH/Materialvetenskap

    Author : Febryana Nugrahany; [2018]
    Keywords : ex-situ catalytic upgrading; slow pyrolysis; screw reactor; fixed bed catalytic reactor; process design;

    Abstract : This study presents a techno-economic assessment of slow pyrolysis of pine sawdust continued by ex-situ catalytic upgrading. The overall process consists of six sections: feed drying, pyrolysis, vapor filtration, ex-situ catalytic upgrading, vapor quenching, and combustion of permanent gas. READ MORE
