1. 11. Concept development to extract sodium sulfate from an aqueous solution

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : André Selander; [2021]
   Keywords : biorefinery; aqueous solution; sodium sulfate; crystallisation; crystallization; kraft process;

   Abstract : Now when the interest is increasing to reach a sustainable infrastructure, one possibility SCA is experimenting with is the possibility to produce renewable hydrocarbons from black liquor which can be extracted from a Kraft process. However, when extracting the black liquor, a lot of sodium-based compounds are removed from the recovery process and when hydrocarbons are produced in SCA’s biorefinery, these compounds are caught in an aqueous solution.

3. 12. Spruce bark biorefinery

   University essay from KTH/Fiber- och polymerteknologi

   Author : Leon Ahlström; Rebecca Mattsson; Hampus Eurén; Alicia Lidén; [2021]
   Keywords : Norway spruce bark; bark biorefinery; extractives; cellulose; lignin; non-cellulose; polysaccharides; soxhlet extraction; hot-water extraction; organosolv extraction; PAA; delignification; carbohydrate analysis; 2D HSQC-NMR and FTIR; Granbark; bark bioraffinaderi; lignin; organosolv extraktion; hot-water extraktion;

   Abstract : Spruce Bark contains several fundamental main substances; lignin, non-cellulose polysaccharides, cellulose and extractives. This undergraduate study focuses on developing a process to extract each of these components from spruce bark using a biorefinery concept, with a main focus on extracting lignin without degradation.

4. 13. 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

5. 14. Fractionation of Wheat Bran for Utilisation in Biorefinery

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Gabriella Haag; [2021]
   Keywords : Wheat bran; biorefinery; chemical engineering; vetekli; bioraffinaderi; extraction; Technology and Engineering;

   Abstract : Wheat bran is a by-product from the production of wheat flour. Nowadays wheat bran is mostly used as feed for animals, in the food and baking industry or it is simply burned in open air. READ MORE

6. 15. Process simulation of HMF production from wheat bran and sugar beet pulp

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Matilda Petersson; [2021]
   Keywords : 5-hydroxymethylfurfural; Wheat bran; Sugar beet pulp; Process simulation; Aspen Plus; Biorefinery; Chemical engineering; Technology and Engineering;

   Abstract : Due to the progressing environmental problems related to global warming, the chemical industry is transitioning from fossil to renewable feedstocks. For added environmental benefits, surplus biomass from the agricultural industry which currently does not have any high-value applications can be used for production of chemicals. READ MORE
