1. 1. GASIFICATION-BASED BIOREFINERY FOR MECHANICAL PULP MILLS

   Författare :Jie He; Engstrand Per; Zhang Wennan; Olof Björkqvist; Dahlquist Erik; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gasification; Mechanical Pulping; Bio-fuels; Power Generation; Biomass Residues; ASPEN Plus;

   Sammanfattning : The modern concept of "biorefinery" is dominantly based on chemical pulp mills to create more value than cellulose pulp fibres, and energy from the dissolved lignins and hemicelluloses. This concept is characterized by the conversion of biomass into various biobased products. LÄS MER

3. 2. Techno-economic evaluation of integrated lignocellulosic ethanol production

   Författare :Elisabeth Joelsson; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distillers dried grain with solubles; biorefinery; modelling; Aspen Plus; biogas; logging residues; spruce; wheat straw; wheat grain; heat; integration; pinch analysis; techno-economic evaluation; first generation; second generation; Ethanol; Lignocellulosic material;

   Sammanfattning : Sweden has claimed that it wants to have a fossil-free vehicle fleet in 2030 as a milestone of its ambitious goal for 2050 to be a country with a sustainable and resource-efficient energy supply without any net GHG emissions. Production of bioethanol from plant materials is one potential method of meeting this goal. LÄS MER

5. 4. Waste-integrated biorefineries : A path towards efficient utilization of waste

   Författare :Chaudhary Awais Salman; Jinyue Yan; Eva Thorin; Mika Järvinen; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gasification; Pyrolysis; Anaerobic digestion; Process integration; Aspen Plus; Ebsilon; Techno-economic analysis; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Waste-management systems have progressed from landfilling and dumping to waste prevention, recycling and resource recovery. In state-of-the-art waste-management industries, waste is separated into various fractions and treated with suitable processes. LÄS MER

7. 5. System studies of MCFC power plants

   Författare :Benny Fillman; Pehr Björnbom; Professor Mats Westermark; Gábor Merényi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel cells; fuel cell systems; system studies; process simulation; molten carbonate; Brennstoffzellen; Brennstoffzellensystem; Systemanalyse; Prozeßsimulation; Bränsleceller; bränslecellssystem; systemstudier; processimulering; smältkarbonatbränslecell; Chemical engineering; Kemiteknik;

   Sammanfattning : Die Brennstoffzelle ist ein elektrochemischer Reaktor und wandelt chemisch gebundene Energie direkt in elektrische Energie um. In der stationären Energieerzeugung ist der Brennstoffzellenstapel selbst nur ein kleiner Bestandteil des vollständigen Systems. LÄS MER
