  1. 1. Aspects of Ash Transformations in Pressurised Entrained-Flow Gasification of Woody Biomass Pilot-scale studies

    Författare :Charlie Ma; Marcus Öhman; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; woody biomass; gasification; ash transformation; slag behaviour; refractory corrosion; Energy Engineering; Energiteknik;

    Sammanfattning : Pressurised entrained-flow gasification (PEFG) of woody biomass has the potential to produce high purity syngas for the production of vital chemicals, e.g., biofuels. However, ash-related issues such as reactor blockages and refractory corrosion need to be addressed before this potential can be realised from a technical perspective. LÄS MER

  2. 2. Bio-based barriers from wood hydrolysates : A pilot-scale approach

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Soheil Saadatmand; Ulrica Edlund; Youssef Habibi; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood hydrolysate; biorefinery; oxygen permeability; multilayer barriers; food packaging.; vedhydrolysat; syrgaspermeabilitet; barriärskikt; livsmedelsförpackning;

    Sammanfattning : Wood hydrolysates (WHs) are liquids extracted from the hydrothermal treatment of wood. They exist as the byproduct of forestry industries such as the dissolving pulp and fiberboard industries. WHs are hemicellulose-based with a large share of lignin in the chemical composition.

  3. 3. From torrefaction to gasification Pilot scale studies for upgrading of biomass

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Martin Strandberg; Anders Nordin; Linda Pommer; Jaap Kiel; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Torrefaction; biomass; pilot scale; continuous reactor; grindability; entrained flow gasification; degree of torrefaction; biomass powder;

    Sammanfattning : Increasing the share of biomass, preferably by replacing fossil fuels, is one way to mitigate the present climate change. Fossil coal can be directly replaced by co-combustion of coal and biomass and fossil engine fuels (gasoline and diesel) could potentially partly be replaced by synthetic renewable fuels produced via entrained flow gasification of biomass.

  4. 4. Entrained-Flow Gasification of Black Liquor and Pyrolysis Oil Experimental and Equilibrium Modelling Studies of Catalytic Co-gasification

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Yawer Jafri; Rikard Gebart; Martin Seemann; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Black liquor; pyrolysis oil; catalytic gasification; co-gasification; gasification; entrained-flow gasification; pilot-scale; Energy Engineering; Energiteknik;

    Sammanfattning : The last couple of decades have seen entrained-flow gasification of black liquor (BL) undergo an incremental process of technical development as an alternative to combustion in a recovery boiler. The ability of the technology to combine chemical recovery with the production of clean syngas renders it a promising candidate for the transformation of chemical pulp mills into integrated forest biorefineries.

  5. 5. Slag Formation During Pilot-Scale Pressurised Entrained-Flow Gasification of Woody Biomass

    Detta är en avhandling från Luleå tekniska universitet

    Författare :Charlie Ma; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Sammanfattning : Pressurised entrained‐flow gasification (PEFG) of sustainable woody biomass offers the opportunity for envi-ronmentally benign production of syngas that is suitable for synthesis of fuels and other chemicals. During the PEFG process, ash-forming matter in the fuel undergoes transformations. LÄS MER
