  2. 1. Biomass in a Sustainable Energy System

    Author : Pål Börjesson; Miljö- och energisystem; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kontroll av utsläpp; Miljöteknik; pollution control; Environmental technology; economic valuation; environmental impact; carbon dioxide; Biomass; energy efficiency; Energiforskning; Energy research;

    Abstract : The increased use of biomass for energy is as a key strategy in reducing carbon dioxide (CO2) emission, which represents the largest anthropogenic contribution to the greenhouse effect. In this thesis, aspects of an increase in the utilisation of biomass in the Swedish energy system are treated. READ MORE

  4. 2. Biomass-fuelled PEM FuelCell systems for small andmedium-sized enterprises

    Author : Tingting Guan; Per Alvfors; Mohsen Assadi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PEMFC; renewable hydrogen production; biomass; hydrogen-rich gas; biomass conversion; anaerobic digestion; steam reforming; CO removal; gasification; sustainable energy system;

    Abstract : Biomass-fuelled proton exchange membrane fuel cells (PEMFCs) offer asolution for replacing fossil fuel for hydrogen production. Through using thebiomass-derived hydrogen as fuel, PEMFCs may become an efficient andsustainable energy system for small and medium-sized enterprises. READ MORE

  5. 3. Biomass Pre-treatment for the Production of Sustainable Energy : Emissions and Self-ignition

    Author : Katarina Rupar-Gadd; Mehri Sanati; Evert Ljungström; Växjö universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; terpenes; SPME; biomass; pellets; self-ignition; storage; drying; calorimetry; Chemical engineering; Kemiteknik; Bioteknik; Biotechnology;

    Abstract : Organic emissions with focus on terpenes, from biomass drying and storage were investigated by Solid Phase Microextraction (SPME) and GC-FID and GC-MS. The remaining terpenes in the biomass (Spruce and pine wood chips) after drying were dependant on the drying temperature and drying medium used. READ MORE

  6. 4. Catalyst Design for the Valorisation of Biomass-derived Furans into Aromatics

    Author : Guido J.L. de Reijer; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; aromatics; 2; 5-dimethylfuran; gallium; biomass; furans; production of aromatics; zeolites; biomass conversion; catalysis;

    Abstract : Anno 2023, mankind must strive towards a more sustainable chemical industry; one that does not solely rely on fossil fuels but also utilises renewable feedstocks such as biomass. Biomass can be catalytically converted into commodity chemicals such as aromatics, through intermediates like furans. READ MORE

  7. 5. Turbomachinery in Biofuel Production

    Author : Martin Görling; Mats Westermark; Simon Harvey; Bengt Hylander; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bio-Methanol; Biomass; Gasification; Humidification; Hybrid Cycle; SNG; Chemical energy engineering; Kemisk energiteknik;

    Abstract : The aim for this study has been to evaluate the integration potential of turbo-machinery into the production processes of biofuels. The focus has been on bio-fuel produced via biomass gasification; mainly methanol and synthetic natural gas. The research has been divided into two parts; gas and steam turbine applications. READ MORE
