  1. 21. Modeling transport phenomena with COMSOL Multiphysics - Adsorptive membrane fouling in lignocellulosic biorefineries and lessons learned from it

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Linnéa Petersson; [2020]
    Nyckelord :QCM-D; Quartz crystal microbalance with dissipation monitoring; Hemicellulose; GGM; Galactoglucomannans; Adsorption; Membrane fouling; COMSOL; Chemical engineering; Kemiteknik; Technology and Engineering;

    Sammanfattning : The separation of hemicelluloses, like glactoglucomannans, from lignocellulosic process streams is an important step in building profitable lignocellulosic biorefineries. The most common method for the separation is membrane filtration, however, it has the draw-back of being sensitive to membrane fouling. LÄS MER

  3. 22. Defining Black: Characterization of Soot Reactivity with Thermogravimetrical Methods : Definiera svart: Karaktärisering av sotreaktivitet med termogravimetriska metoder

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Adarsh Roy Choudhury; [2020]
    Nyckelord :Diesel Particulate Filter; Chemical Kinetics;

    Sammanfattning : Exhaust emissions in a vehicle has to flow through an exhaust aftertreatment in a diesel vehicle. In a diesel engine, the exhaust emissions are treated with Diesel Oxidation Catalyst (DOC), Diesel Particulate Filter (DPF), and Selective Catalytic Reduction (SCR). Every engine produces a different kind of soot depending on the drive cycle. LÄS MER

    Sammanfattning : Effects of carbon functionalization on the catalytic properties of the space underneath epitaxial graphene flakes on Ir(111) are investigated with Ambient Pressure X-ray Photoelectron Spectroscopy studies of oxygen hydrogenation. The 0. LÄS MER

  5. 24. Downscaling and modelling of an ion-exchange chromatography column for purifying glucose solutions

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Viktor Geraldsson; [2020]
    Nyckelord :Ion-exchange; chromatography; glucose; purification; modelling; equilibrium isotherm; Matlab; chemical engineering; kemiteknik; Technology and Engineering; Chemistry;

    Sammanfattning : To utilize sugars as a feedstock for renewable industries, the feedstock often needs to be very pure. This is due to ionic species contaminating the sugar feedstock being potent catalyst poisons in many cases. To remove ionic species from the sugar feedstock, it is dissolved and purified using packed ion-exchange columns. LÄS MER

  7. 25. The Effect of Using DMSO as a Cosolvent for Ligand Binding Studies

    Master-uppsats, Lunds universitet/Biofysikalisk kemi

    Författare :Simon Birgersson; [2019]
    Nyckelord :Galectins; Nuclear Magnetic Resonance; NMR; Biophysical Chemistry; Relaxation; CPMG; ITC; Biofysikalisk Kemi; Kärnmagnetisk resonans; Technology and Engineering; Chemistry; Biology and Life Sciences;

    Sammanfattning : DMSO sees common application as a solvent for studies of synthetic molecules in biological systems, in fields such as drug design. Despite this, the possibility and nature of solvent interactions with both synthetic ligand and their target macromolecules is widely unexamined. LÄS MER
