    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Lina Näslund; Gabriella Petersson; [2023]
    Keywords : Membrane filtration; Ultrafiltration; Microfiltration; Dialcohol cellulose; DAC; Bioplastics; Chemical engineering; Process design; Technology and Engineering;

    Abstract : The waste management and production of plastic play a concerning part in global warming and continues to have a negative effect on the environment. A promising strategy to address this challenge is to develop new sustainable materials, to replace current fossil-based plastics. READ MORE

  3. 2. Lignin modification for higher reactivity towards epoxides

    University essay from KTH/Fiber- och polymerteknologi

    Author : Filip Rynkiewicz; [2023]
    Keywords : Lignin; modification; reactivity; epoxide; oxidation; Lignin; modifikation; reaktivitet; epoxid; oxidation;

    Abstract : Fem metoder har använts för att modifiera barrvedslignin med syftet att öka reaktiviteten av ligninet mot epoxidgrupper. Ligninprover analyserades med NMR och FTIR medan reaktivitet var mätt genom reometri. Metoder som ökade mängden karboxylsyragrupper på ligninet minskade ligninets reaktivitet. READ MORE

  4. 3. Alkaline wet oxidation of biorefinery lignin from wheat straw

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Maja Lindblad; [2021]
    Keywords : alkaline wet oxidation; lignin oxidation; wheat straw; chemical pretreatment; biorefinery lignin; anaerobic digestion; response surface-modelling; chemical engineering; Technology and Engineering;

    Abstract : Climate change and depletion of fossil resources have generated a need for energy production based on renewable resources such as lignocellulosic biomass. Agricultural residues, like wheat straw, is lignocellulosic biomass that could contribute to the energy supply if it was used for biogas production. READ MORE
