  1. 16. Understanding particulate matter - Material analyses of real-life diesel particulate filters and correlation to vehicles’ operational data

    University essay from KTH/Kemiteknik

    Author : Linus Nordin; [2021]
    Keywords : Diesel particulate filter; Ash measurement method development; Correlation study; Operational parameters; Principal component analysis; Dieselpartikelfilter; Askanalys metodutveckling; Korrelationsstudie; Driftsparametrar; Principal component analysis;

    Abstract : Syftet med denna studie var att undersöka effekterna av driftsparametrar på ett antal mätbara askrelaterade parametrar i dieselpartikelfilter (DPF) i tunga fordon. Tidigare studier visar att askans packningsdensitet, askflöde och hur askan fördelas inuti ett DPF är beroende av parametrar som temperatur, avgasflöde och oljeförbrukning ett fordon har. READ MORE

  3. 17. Agricultural waste and wood waste for pyrolysis and biochar : An assessment for Rwanda​

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Jenny Eliasson; Viktor Carlsson; [2020]
    Keywords : Biochar; Pyrolysis; Biochar feedstock characteristics; Agricultural waste; Composition crop residues; Wood waste; Agricultural production Rwanda; Ultimate analysis; Structural composition; Heating Value; RPR; Biokol; Pyrolysis; Råmaterialegenskaper biokol; Jordbruksavfall​; Sammansättning jordbruksavfall; Träavfall; Jordbruksproduktion Rwanda; Värmevärde;

    Abstract : A high priority in order to combat climate change is disposal of waste. In low-income countries, a large portion of biomass residues generated in the forestry, agricultural and industrial sectors could be usable, instead of being seen as waste. For instance, it could be converted into biochar, which is proven to have many environmental benefits. READ MORE

  4. 18. Use of Agricultural Wastes as Supplementary Cementitious Materials

    University essay from KTH/Byggvetenskap

    Author : Ezio Marchetti; [2020]
    Keywords : Agricultural waste; Environmental impact; Concrete; Life Cycle Assessment; Oat husk ash; Rice husk ash; Supplementary cementitious materials; Sustainable Construction; Betong; Havreskalaska; Hållbar konstruktion; Jordbruksavfall; Kompletterande cementmaterial; Livscykelanalys; Miljövarudeklaration; Miljöpåverkan; Risskalaska;

    Abstract : Global cement production is continuously increasing from 1990 till 2050 and growing particularly rapidly in developing countries, where it represents a crucial element for infrastructure development and industrialisation. Every tonne of ordinary Portland cement (OPC) produced releases, on average, about 800 kg of CO2 into the atmosphere, or, in total, the overall production of cement represents roughly 7% of all man-made carbon emissions.

  5. 19. Burning material behaviour in hypoxic environments: An experimental study examining fire dynamics of composite materials in vitiated conditions

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Robert Bray; [2020]
    Keywords : ORS; Fire engineering; hypoxic; polymers; Technology and Engineering;

    Abstract : The progression of fire safety research has contributed to improving the guiding principles of standardised building design. Research making use of pure materials, once common in homes and workplaces, are less relevant as such materials are no longer as prevalent. READ MORE

  6. 20. Development of a Near Infrared Spectroscopy Model for Prediction of Fibre Compounds in Alfalfa

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Christina Andersen; [2020]
    Keywords : alfalfa; lucerne; medicago sativa; green protein powder; NIR; near infrared spectroscopy; model development; matlab; PLS; partial least squares; PCA; principal component analysis; SNV; standard normal variate; fibre prediction; TDF; total dietary fibre; applied microbiology; teknisk mikrobiologi; Technology and Engineering;

    Abstract : Background: This project investigates if it is possible to develop a calibration model from near infrared (NIR) spectroscopic measurements, for determination of the amount and type of fibre fractions within protein powder produced from the legume alfalfa, without performing wet experiments. Alfalfa is also known as Medicago sativa and lucerne, but is in this project further referred to as alfalfa. READ MORE
