  1. 1. Characterization of NiMo catalysts with noble metal promoters

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Filip Hallböök; [2023]
    Nyckelord :Catalysis; Hydrodeoxygenation; TPR; NiMo-catalysts; Chemical engineering; Chemistry;

    Sammanfattning : To be able to face the challenges brought on by climate change there is an urgent need to reduce the heavy dependence on fossil fuels. Bio-oil is one such renewable and carbon-neutral replacement that has shown promising potential. A key step in making bio-oil commercially feasible is improvements of the upgrading processes of the bio-oil. LÄS MER

  3. 2. Nanoscale characterisation of model Ni-Mo catalyst active phases

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Centrum för analys och syntes

    Författare :Jonas Elmroth Nordlander; [2022]
    Nyckelord :Ni-Mo catalysts; Hydrodeoxygenation; TEM; PXRD; Materials chemistry; Chemistry;

    Sammanfattning : An important stepping stone in transitioning from a fossil-fuel based transportation system is the production of bio-fuels such as bio-oils. For bio-oils to be commercially viable, catalytic upgrading via hydrodeoxygenation is required, typically using Ni-Mo oxide or sulfide catalysts. LÄS MER

  4. 3. Partial hydrodeoxygenation of a heavy bio-based oil fraction : (A technical feasibility study)

    Master-uppsats, KTH/Kemiteknik

    Författare :Akshay Menon; [2020]
    Nyckelord :Hydrodeoxygenation; Tall oil pitch; oxygen removal; sulphidation; catalyst;

    Sammanfattning : This report is intended to provide the reader with an extensive background information on hydrode oxygenation (HDO) of Tall Oil Pitch (TOP), combined with results from chemical property analyses of the same. Firstly, the importance of hydrogenation and oxygen removal for a biomass-based feed material is highlighted. LÄS MER

  5. 4. Hydrodeoxygenation of Pyrolysis Oil: Comparing an Iron-based Catalyst with Dolomite

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

    Författare :Dennis Fällén Holm; [2017]
    Nyckelord :Biomass; bio-oil; bio-crude; hydrodeoxygenation; pyrolysis and tar cracking.;

    Sammanfattning : This thesis evaluates the possibility to use a iron-based catalyst as a pyrolysis vapour conversion catalyst. The iron catalyst was also compared with the mineral dolomite. LÄS MER
