  1. 16. Investigation of Milled Wood Lignin Extraction Using Enzymatic Hydrolysis for Application in Hydrophobic Barriers in the Food Packaging Industry

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Anna Wagne; [2023]
    Keywords : Lignin; extraction; hydrophobicity; chemical engineering; Technology and Engineering;

    Abstract : The objective of this report is twofold: to optimise the extraction method of lignin from spruce altering a few process parameters and to investigate the use of lignin as a hydrophobic barrier in food applications. The process used was STEX (steam explosion) pretreatment followed by enzymatic hydrolysis and MWL (milled wood lignin) extraction using a mixture of dioxane-water. READ MORE

  3. 17. Investigation of flux dependence on viscosity in ultrafiltration

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Peter Bourghardt; [2023]
    Keywords : ultrafiltration; viscosity; molasess; konjac glucomannan; comsol; LabStak M39; membrane; filtration; chemical engineering; Chemistry;

    Abstract : This project aims to compare the effect of viscosity on flux for high viscosity liquids. The performance of two different viscous solutions was studied in a plate-and-frame membrane module. READ MORE

  4. 18. Mathematical Modeling and Simulation of Cryogenic Liquid Hydrogen Storage

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Gusten Zandler Andersson; [2023]
    Keywords : Modeling; Simulation; Liquid Hydrogen; Storage tank; Modelica; Chemical engineering; Technology and Engineering;

    Abstract : Liquid hydrogen is an attractive alternative to fossil fuels in the aviation industry, but storing it both before and during flights introduces many challenges pertaining to the cryogenic liquid conditions required. Having reliable models to predict the dynamical behavior inside the storage tank is therefore of great interest. READ MORE

  5. 19. Biodiesel production from rape seed oil catalyzed by calcium oxide doped with lithium

    University essay from KTH/Kemiteknik

    Author : Abdulbasit Abdalla; Emilia Odgren; [2023]
    Keywords : Biodiesel; transesterifiering; FFA; glycerol; FAME; förtvålningsreaktion; Li-CaO; BET; EDS; SEM; heterogena katalysatorer; utbyte; kinetik;

    Abstract : Biodiesel ses som ett av de främsta substituten för fossila bränslen, då den relativt enkelt kan appliceras i redan existerande dieselmotorer. Dagens produktion av biodiesel använder sig av homogena katalysatorer som inte återanvänds i processen, men för en mer cirkulär och i längden en billigare process ses heterogena katalysatorer som ett alternativ.
