  1. 1. The mechanism behind internal injector deposits

    University essay from KTH/Kemiteknik

    Author : Jenny Blomberg; [2023]
    Keywords : Biodiesel; deposit formation; engine oil; calcium sulphate; internal diesel injector deposits; Biodiesel; beläggningsbildning; motorolja; kalciumsulfat; interna dieselinjektorbeläggningar;

    Abstract : Användningen av biobränslen har ökat för att minska utsläppen från fossila bränslen. Biobränslen kan dock leda till beläggningar inuti injektorn, vilka påverkar fordonets  körbarhet. READ MORE

  2. 2. Analysis of Methanol Based Chlorine Dioxide Production : An analysis of sodium chlorate reduction efficiency and investigation of salt cake filter wash on an SVP-LITE® system

    University essay from Karlstads universitet

    Author : Emil Lundh; [2023]
    Keywords : ECF; SVP-LITE®; chlorine dioxide; bleaching; ECF; SVP-LITE®; Klordioxid; blekning;

    Abstract : This work aimed to determine how effective an SVP-LITE® chlorine dioxide plant at Vallviks Bruk was running. This was done by determining the chemical consumption per unit of chlorine dioxide produced. The calculations relied upon online instrumentation that was manually validated. READ MORE

  3. 3. Wet Spinning of Cellulose-Lignin Precursor for Carbon Fibers : Effect of Coagulation Bath Composition & Spin Finish

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Julia Sundmark; [2023]
    Keywords : Carbon fiber; Cold alkali; Cold NaOH; lignin; cellulose; wet spinning; Kolfiber; kallalkali; lignin; cellulosa; våtspinning;

    Abstract : Carbon fibers (CF) are a material with a composition of over 90% carbon, which has high mechanical properties and low density. This unique combination of properties makes it requirable in applications such as vehicles, aerospace, wind power, and space industries. Commercially made CF are made using the fossil raw material polyacrylonitrile (PAN). READ MORE

  4. 4. Swedish “tofu” from faba beans : a textural and structural analysis

    University essay from SLU/Department of Molecular Sciences

    Author : Saga Preis; [2023]
    Keywords : Tofu; faba bean; Vicia faba; texture; microstructure;

    Abstract : Tofu, a traditional soybean product, is a popular plant-based alternative which could potentially be produced from Swedish-grown faba beans (Vicia faba L.). The aim of this project was to asses the viability of producing a tofu-like faba bean product using food grade gypsum (calcium sulphate) as coagulant. READ MORE

  5. 5. Characterization of a novel bacteriumoriginating from a biogas process

    University essay from SLU/Department of Molecular Sciences

    Author : Louise Welén; [2023]
    Keywords : biogas; ammonia-tolerance; mesophilic; characterization; bacterium;

    Abstract : An anaerobic bacterium, isolated from an enrichment culture originating from a biogas reactor operating at high ammonia conditions, was characterised via various tests. An analysis of the 16S rRNA gene confirmed that the closest relative was Desulfotomaculum halophilum with 92,5 % similarity. READ MORE
