  1. 11. Friction and Wear Performance of Experimentally Developed Self-lubricating PPS/PTFE Composites

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

    Author : Kimberly Rose Lagrama; [2019]
    Keywords : PPS; PTFE; self-lubricating composites;

    Abstract : Demanding applications, as well as the push to eliminate the need for fossil-fuel based lubricants, create the need for the development of high-performance polymers. Polyphenylene Sulfide (PPS) is an example of a high-performance polymer and has a high service temperature, good dimensional stability, and excellent chemical resistance. READ MORE

  3. 12. Catalytic hydrotreating of lignin

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Markus Lilja; [2019]
    Keywords : Lignin; hydrotreating; kemiteknik; chemical engineering; Chemistry; Technology and Engineering;

    Abstract : One of the main challenge’s society faces today is climate change caused by CO2 due to the de-pendence on fossil fuels. To combat the increasing CO2 levels there is a need to develop renewable fuels. One such fuel could potentially be derived from lignin. In this thesis, lignin derived from a pulp and paper mill was first treated and cleaned. READ MORE

  4. 13. Intensification of lignocellulosic bioethanol production process using multi-staged membrane bioreactors

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Clarisse Uwinez; [2019]
    Keywords : Interconnected continuous hydrolysis and fermentation; lignocellulosic bioethanol; Membrane bioreactors; process intensification; lignin recovery; membrane fouling.;

    Abstract : The exploitation of lignocellulosic materials with the aim of producing high value-added products will potentially counteract concerns related to the depletion of fossil resources or exponential population growth. Bioethanol produced from lignocellulosic agriculture residue exhibits promising alternative to the petroleum-based fossil fuel which reduces net emission of greenhouse gases (GHG). READ MORE

  5. 14. Development of a modern catalytic system for the production of C3+ aliphatic alcohols by the Fischer-Tropsch method

    University essay from KTH/Energiteknik

    Author : Aravind Ganesan; [2019]
    Keywords : syngas; Cobalt; Fischer-Tropsch; alcohols; hydrocarbons; syngas; kobolt; Fischer-Tropsch; alkoholer; kolväten;

    Abstract : This thesis deals with converting a mixture of H2 and CO, also referred to as syngas or producer gas, to higher or mixed alcohols and other fuels through a process called Fischer Tropsch Synthesis (FTS). It is a beneficial pathway that minimizes the dependence on oil and similar fossil fuels which contribute to rapid climate change by releasing harmful greenhouse gases. READ MORE

  6. 15. Development of a method that quantifies the filtration efficiency of soft particles in drop-in fuels

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Swarga Shriharsha; [2019]
    Keywords : ;

    Abstract : The global carbon footprint is increasing with course of time. World is moving towards fossil free and reduce the dependency of fossil fuels to meet their daily needs. Transportation industry is the major user of fossil fuels today and major contributor to the CO2 emissions which leads to global warming. READ MORE
