  4. 7. Hydrothermal Liquefaction of Kraft Lignin - The influence of capping agents and residence time

    Author : Anders Ahlbom; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; HTL; hydrothermal liquefaction; isopropanol; residence time; kraft lignin;

    Abstract : In the context of exploring alternatives to replace fossil resources, lignin has been acknowledged as a renewable source of various aromatic compounds that have the potential of being precursors to chemicals as well as fuel additives. Originating from lignocellulosic biomass such as wood, lignin is an amorphous polymer with a high content of aromatic units and, in order to harness these units, it must be depolymerised. READ MORE

  5. 8. Catalytic Upgrading of Waste Oils to Advanced Biofuels – Deactivation and Kinetic Modelling Study

    Author : Prakhar Arora; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Stearic acid; TEM; Advanced biofuels; NiMo; Catalytic HDO; MoS2; Kinetic modelling; Oleic acid; Hydrodeoxygenation;

    Abstract : The demand for liquid hydrocarbons as transportation fuels is enormous and ever growing. Advanced biofuels is one of the promising solutions to keep pace with the global transition to cleaner energy by reducing greenhouse gas emissions from the transport sector. READ MORE

  6. 9. Design and Operation of a 10 kWth Chemical-Looping Combustor for Solid Fuels

    Author : Nicolas Berguerand; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Interconnected Fluidized Beds; Oxygen Carrier; Chemical-Looping Combustion; Carbon Dioxide Capture; Solid Fuel Conversion;

    Abstract : The use of a 10 kWth chemical-looping combustor for solid fuels was investigated. The unit was designed, dimensioned and built and two types of fuel were tested: a South African coal and a petroleum coke from Mexico. Chemical-looping combustion is an alternative to normal combustion for CO2 capture. READ MORE

  7. 10. Norbornadienes for Solar Thermal Energy Storage and New Applications

    Author : Ambra Dreos; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; thermal energy storage; molecular logic; Solar energy; molecular switch- es; energy conversion; quadricyclane; molecular keypad locks; norbornadiene;

    Abstract : The energy demand worldwide is steadily increasing, therefore it is fundamental to efficiently utilise renewable energy resources. Energy storage technologies are partic- ularly relevant in order to be able to exploit renewable energy resources such as solar energy, since these are typically intermittent and not evenly distributed.
