  2. 1. Mitigating Off-Gassing and Self-Heating in Fuel Wood Pellets Storage : A Raw Materials Selection and Pre-Treatment Centred Approach

    Author : Workson Siwale; Jonas Berghel; Gunnar Henriksson; Michael Finell; Stefan Frodeson; Mani Sudhagar; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solid biofuels; densified biomass; heat generation; off-gas emissions; carbon monoxide; carbon dioxide; methane; fatty and resin acids; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : Wood pellets have become a preferred solid biomass fuel for heat and power generation due to their standardized nature, known properties, and consistent quality. However, pellets produced from fresh sawdust sometimes undergo self-heating and off-gassing during storage. This poses a challenge for their transportation and storage. READ MORE

  4. 2. Electrooxidation of glycerol and methanol on gold

    Author : Mikael Valter; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; van der Waals; electrochemistry; methanol; gold; glycerol; DFT;

    Abstract : Burning of fossil fuels leads to excess CO2 in the atmosphere, causing global warming, threatening civilisation and ecosystems worldwide. As a step in making the society fossil-independent, we need to replace oil, coal, and gas in the transportation sector with fuels originating from sustainable energy. READ MORE

  5. 3. Understanding the Influence of Wood Extractives on Off-Gassing during Storage of Wood Pellets

    Author : Workson Siwale; Jonas Berghel; Gunnar Henriksson; Michael Finell; Stefan Frodeson; Gunnar Johansson; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Off-gassing; Carbon Monoxide; Carbon Dioxide; Methane; Self-heating; Additive Oils; Fatty and Resin Acids; Solid Biofuels; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : Wood pellets have become a solid biomass fuel of choice because they are a standardized product with known quality properties. However, the self-heating and off-gassing tendencies during storage of wood pellets threatens the consistency of the pellets’ quality properties. READ MORE

  6. 4. Fischer-Tropsch Synthesis over Cobalt-based Catalysts for BTL applications

    Author : Matteo Lualdi; Christofer Leygraf; Roy Johnsen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cobalt; Fischer-Tropsch; syngas; selectivity;

    Abstract : Fischer-Tropsch synthesis is a commercial technology that allows converting synthesis gas, a mixture of CO and H2, into fuels and chemicals. This process could be one of the actors in the reduction of oil dependency of the transportation sector. READ MORE

  7. 5. Studies of hydrocarbon-assisted selective catalytic reduction of nitrogen oxides - DME as reductant and reaction mechanism over silver/alumina

    Author : Stefanie Tamm; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ZSM-5; NCO; HC-SCR; Dimethyl ether; reaction mechanism; silver alumina;

    Abstract : Increasing amounts of carbon dioxide are attaining worldwide growing attention as one probable cause for global warming. Together with the expected peak in oil production and an increasing oil demand, this results in a greater interest in more fuel effective lean burn engines (i.e. operation with excess oxygen).
