  1. 36. Oligomerization of ethylene and ethanol into fuel through heterogenous catalysis

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Mergim Pacolli; Marko Ristovic; [2017]
    Nyckelord :chemical engineering; kemiteknik; Technology and Engineering;

    Sammanfattning : The goal and ambition of this thesis has been to investigate a topic that could lead to a possible solution to the environmental crisis we are witnesses of. Replacement of fossil fuels is an essential step towards a renewable society that needs to be taken. LÄS MER

  3. 37. PILCs for trapping phosphorus in a heavy duty engine exhaust system : An experimental evaluation of the phosphorus sorption capability of different clay materials

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Anders Kvarned; [2016]
    Nyckelord :PILC; PCH; phosphorus sorption; exhaust treatment; catalyst poisoning;

    Sammanfattning : In order to fulfil the requirements in the EURO VI standard, regulating emissions from heavy duty vehicles, the exhaust aftertreatment system needs to maintain its efficiency for at least seven years or 700 000 km. In diesel applications the diesel oxidation catalyst (DOC) is located closest to the engine and is thus the most vulnerable to poisoning contaminants, such as phosphorus originating from fuel and oil additives, which deactivates the catalyst.

  4. 38. Microbial Fuel Cell for Waste Water Treatment

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Fabio Cameli; [2016]
    Nyckelord :Microbial Fuel Cell; Water treatment; Chemical Engineering; Electrochemistry; Energy sustainable process;

    Sammanfattning : Microbial Fuel Cell is a novel technology that can be used for a waste water treatment in order to simultaneously remove carbonaceous matter and nitrogen while producing electrical power. Even if it is not an established technology so far, MFC could be a cost effective option for waste water treatment and the major challenge of this process will be the device scale-up. LÄS MER

  5. 39. Fully Glazed Office Building Façade Designs in Denmark

    Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Författare :Giedre Villekjær Pedersen; [2016]
    Nyckelord :glazed façade; thermal comfort; visual comfort; window properties; DGNB certification; Building Class 2020; low-energy design strategies; office building; LCC; Technology and Engineering;

    Sammanfattning : The current trend in office building architecture includes large glazed areas that give transparent architecture. But these buildings have a challenging indoor climate and a higher energy use than required by current building regulations in Denmark. LÄS MER

  7. 40. Hörselnedsättning hos barn och ungdomar till följd av platinabaserad kemoterapi - en beskrivande litteraturstudie

    Kandidat-uppsats, Göteborgs universitet/Institutionen för neurovetenskap och fysiologi

    Författare :Ino Alagic; [2015-06-22]
    Nyckelord :platinum chemotherapy; ototoxicity; hearing loss; children;

    Sammanfattning : Framgång i behandling med platinabaserad kemoterapi mot olika typer av cancertumörer begränsas av biverkningar i form av bland annat hörselnedsättning som kan ha stor påverkan på den enskildes livskvalité. Det är av stor vikt att fortsätta med studier som lyfter upp denna problematik. LÄS MER
