  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. Development of a Novel Biocatalytic Cascade for the Valorisation of 5-(Hydroxymethyl)furfural

    Master-uppsats, KTH/Industriell bioteknologi

    Författare :Johannes Johansson; [2022]
    Nyckelord :Biocatalysis; Enzyme immobilization; 5- Hydroxymethyl furfural; Transaminase; Galactose Oxidase; Biokatalys; Enzym-immobilisering; 5- hydroxymetyl furfural; Transaminas; Galaktosoxidas;

    Sammanfattning : Den nära förestående bristen på fossila resurser i kombination med deras associerade miljöfarlighet betonar behovet av utveckling av alternativa, mer hållbara kemikalier. I denna studie utvecklades en enzymatisk kaskad för förädling av 5-(hydroxymetyl)furfural (HMF) till 5-(aminometyl)-2-furfuraldehyd (AMFA). LÄS MER

  4. 3. Study of a valorisation process for biomass industrial waste involving acid cooking and enzymatic hydrolysis

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

    Författare :Nicolas Brunet; [2020]
    Nyckelord :;

    Sammanfattning : Lignocellulosic biomass has potential to chip in the chemical and biofuels supplies in future societies,even though lignocellulose is a recalcitrant structure that has to be treated in several steps. After theirproper life cycle, wood-derived materials such as particleboards have few outcomes today apart fromenergy recovery for heat production. LÄS MER

  7. 5. Production of bioethanol from wheat straw hydrolysate using reverse membrane bioreactor (rMBR)

    Uppsats för yrkesexamina på grundnivå, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Jessica Khin San; [2018]
    Nyckelord :Reverse membrane bioreactor; wheat straw; fermentation; ethanol; furfural; diffusion rate;

    Sammanfattning : The second-generation bioethanol production in which lignocellulosic material is used as feedstock faces some difficulties. Lignocellulosic materials have to be pretreated prior to fermentation. LÄS MER
