  1. 1. Biomass gasification in ABFB Tar mitigation

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Nemanova Vera; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ash; biomass; char; gasification; iron-based; petcoke; tar; Chemical Engineering; Kemiteknik;

    Abstract : Biomass gasification may be an attractive alternative for meeting future energy demand. Although gasification is a mature technology, it has yet to be fully commercialised due to tar formation. This study focuses on the tar mitigation in gas produced in an atmospheric bubbling fluidised bed (ABFB) gasification system. READ MORE

  2. 2. Alkali-enhanced gasification of biomass laboratory-scale experimental studies

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Albert Bach-Oller; Luleå tekniska universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alkali; biomass; gasification; tar; soot; potassium; char; syngas; enhanced; Energiteknik; Energy Engineering;

    Abstract : Gasification seeks to break carbonaceous materials into synthetic gas (CO+H2) which can be subsequently upgraded into valuable products. Thus gasification can be utilized to convert low grade biomass stocks into carbon-neutral chemicals heat and power. READ MORE

  3. 3. Refractory corrosion in biomass gasification

    University dissertation from Umeå : Umeå Universitet

    Author : Markus Carlborg; Umeå universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Refractory corrosion; slag; biomass; gasification; Materials Science; materialvetenskap;

    Abstract : To stop the net emission of CO2 to the atmosphere, we need to reduce our dependency of fossil fuels. Although a switch to a bio-based feedstock hardly can replace the total amount of fossils used today, utilization of biomass does still have a role in a future in combination with other techniques.

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

    University dissertation from Umeå : Umeå universitet

    Author : Martin Strandberg; Umeå universitet.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Torrefaction; biomass; pilot scale; continuous reactor; grindability; entrained flow gasification; degree of torrefaction; biomass powder;

    Abstract : 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.

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

    University dissertation from Luleå : Luleå University of Technology

    Author : Yawer Jafri; Luleå tekniska universitet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Black liquor; pyrolysis oil; catalytic gasification; co-gasification; gasification; entrained-flow gasification; pilot-scale; Energy Engineering; Energiteknik;

    Abstract : 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.
