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

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

    Sammanfattning : 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. LÄS MER

  5. 5. Experimental studies of ash transformation processes in combustion of phosphorus-rich biomass fuels

    Författare :Alejandro Grimm; Britt-Marie Steenari; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : The present thesis is a summary of eight papers dealing with experimental studies on bed agglomeration, slag formation, formation of deposits and fine particulate matter during combustion of phosphorus-rich biomass fuels. The experimental procedures were performed in a bubbling fluidized bed (5 kW), two fixed bed appliances (20 and 15 kW) and in a powder burner (150 kW). LÄS MER
