  1. 1. Research on the Hydrothermal Conversion of Xylose Catalysed by CO2-H2O into Furfural

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Robert Liao; [2023]
    Nyckelord :;

    Sammanfattning : Agricultural waste treatment and carbon dioxide emissions from fossil fuel combustion have been critical challenges for sustainable development. This work is part of a study on converting straw into biofuels, which involves using xylose as the material, carbon dioxide (CO2) as the catalyst, and water (H2O) and Gamma-Valerolactone (GVL) as the solvent to produce furfural through hydrothermal conversion.

  3. 2. Integrated membrane reactor for the production of butyl butyrate starting from biomass

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Carlos Rubio; [2023]
    Nyckelord :butyl butyrate; butanol; butyric acid; membrane technology; enzymatic catalysis; butylbutyrat; butanol; smörsyra; membrane teknologi; enzymatisk katalys;

    Sammanfattning : Efterfrågan på energi ökar snabbt, och denna trend förväntas bestå. Det råder dock ingen tvekan om att världen för närvarande befinner sig i en energikris, som är en katastrof både ekonomiskt och miljömässigt. Följaktligen är sökandet efter alternativa energikällor för att ersätta fossila bränslen absolut nödvändigt. LÄS MER

  4. 3. Gene overexpression screens to identify limitations on the productivity of cyanobacteria growth

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Tobias Willi; [2020]
    Nyckelord :Cyanobacteria; Dub-sequencing; competitive growth; overexpression library; Synechocystis 6803; Synechococcus 7002; Synechococcus UTEX 2973; Photobioreactor; Conjugation; mobA;

    Sammanfattning : Cyanobacteria are a model organism for photosynthesis and the Calvin cycle, and a promising chassis for 4th generation biofuel production. There are many ongoing efforts to improve the performance of cyanobacteria, in terms of CO2 fixation and production rate of biofuels. LÄS MER

  5. 4. The ecological footprint of swedish sugar consumption

    Kandidat-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Karin Holmstrand; [2019]
    Nyckelord :land use; sustainability; sugar;

    Sammanfattning : Climate change, loss of biodiversity and an ongoing population growth are challenging the global food production. Land is a scarce resource that is demanded for many purposes, reason why it is relevant to question how the arable land is used in the food production. LÄS MER

  7. 5. A struggle between reality and reliability: The uncertainties of including indirect land use change in life-cycle assessments

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Nathalie Hjulström; [2019]
    Nyckelord :Indirect land use change; life-cycle assessment; biofuel; bio-based plastics; Technology and Engineering; Earth and Environmental Sciences;

    Sammanfattning : Serious questions have been raised about the environmental impacts of biofuels concerning indirect land use change (ILUC) and this concept may also be applied to other products such as bio-based plastics. The purpose of this study is to identify the uncertainties of including ILUC in life-cycle assessments. LÄS MER
