  1. 1. Biofuels from Kraft Black Liquor Pilot-Scale Gasification Development and Techno-Economic Evaluation of Industrially Relevant Biofuel Production Pathways

    University dissertation from Luleå University of Technology

    Author : Yawer Jafri; Luleå tekniska universitet.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofuels; black liquor; pyrolysis oil; gasification; drop-in; energy systems; techno-economic; Energiteknik; Energy Engineering;

    Abstract : Fuel combustion for transport was responsible for 24% of EU-28 greenhouse gas (GHG) emissions in 2016. Member states are expected to ensure that the share of renewable energy in the transport sector is at least 14% by 2030. Some countries, such as Sweden, have more ambitious targets. READ MORE

  2. 2. New refrigerants for vapour compression refrigeration and heat pump systems : evaluation in a context of the requirements set by the F-gas Regulation and the Paris Agreement goals

    University dissertation from Universitetsservice US-AB

    Abstract : Replacing fossil fuels with alternatives derived from renewable sources is one way of meeting society’s increasing need for mobility while also significantly reducing greenhouse gas emissions from vehicles with internal combustion engines. To facilitate such a replacement, this thesis presents optical spray studies and engine experiments conducted to evaluate the potential of blends of biomass-derived alcohols and vegetable oils to serve as drop-in fuels for compression ignition engines.
