1. 1. Recovery of Dialcohol Cellulose using Micro- and Ultrafiltration Processes

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

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

   Sammanfattning : 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. LÄS MER

3. 2. Microgrid in George Washington, Cuba

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Mimmi Fröjdh; Sofia Sjöberg; [2023]
   Nyckelord :Cuba; microgrid; energy systems modelling; renewable energy; optimization; Kuba; microgrid; energisystemmodellering; förnybar energi; optimering;

   Sammanfattning : Cuba has vast natural resources for domestic renewable energy generation, but their energy mix is heavily dominated by fossil fuels. This contributes to a high dependence on expensive oil imports and has led to significant generation shortfalls, which in turn has resulted in extensive power outages and serious fuel crises.

4. 3. Analysis of Microgrid Electrification on Phaluai Island : A Minor Field Study in Thailand

   Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Leontina Walldén; Caroline Wahlberg; [2023]
   Nyckelord :Microgrid; Rural electrification; Rural islands; Thailand; Renewable energy; Microgrid; Elektrifiering av landsbygd; Isolerade öar; Thailand; Förnybar energi;

   Sammanfattning : Similar to numerous other nations, Thailand aims to achieve carbon neutrality by 2050 by reducing reliance on fossil fuels and increasing the amount of renewable energy sources in electricity generation. The objective of the Thai Provincial Electricity Authority (PEA) is to ensure electricity access for all Thai households and villages. LÄS MER

5. 4. Leveraging green hydrogen to decarbonise the aviation industry : A case study on electrofuels in Sweden

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Jakob Bergene; Jonathan Bruchhausen; [2023]
   Nyckelord :Electrofuel; e-fuel; electrokerosene; e-kerosene; SAF; sustainable aviation fuel; sustainable aviation; complementarity formation mechanisms; technology value chains; TVC; Techno-economic analysis; TEA; Elektrobränsle; e-bränsle; elektrofotogen; e-fotogen; SAF; sustainable aviation fuel; sustainable aviation; komplementära formationsmekanismer; technology value chains; TVC; Techno-economic analysis; TEA;

   Sammanfattning : For the EU to reach its 2050 climate targets the aviation industry that is highly dependent on fossil fuels needs to drastically reduce its emissions. In the decarbonisation of the aviation industry drop-in sustainable aviation fuels (SAFs) have been identified as a promising solution to abate the industry’s emissions. LÄS MER

7. 5. Characterization of NiMo catalysts with noble metal promoters

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Filip Hallböök; [2023]
   Nyckelord :Catalysis; Hydrodeoxygenation; TPR; NiMo-catalysts; Chemical engineering; Chemistry;

   Sammanfattning : To be able to face the challenges brought on by climate change there is an urgent need to reduce the heavy dependence on fossil fuels. Bio-oil is one such renewable and carbon-neutral replacement that has shown promising potential. A key step in making bio-oil commercially feasible is improvements of the upgrading processes of the bio-oil. LÄS MER
