  2. 1. Biomass gasification in ABFB : Tar mitigation

    Author : Nemanova Vera; Klas Engvall; Joan Salvadó; KTH; []
    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

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

    Author : Martin Strandberg; Anders Nordin; Linda Pommer; Jaap Kiel; Umeå universitet; []
    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. 3. High temperature corrosion in biomass-fired energy applications : Alloying effects and test environment comparisons

    Author : Ragna Elger; Rachel Pettersson; Inger Odnevall Wallinder; Rikard Norling; Gordon Tatlock; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; High temperature corrosion; biomass; waste; superheater corrosion; austenitic steel; biomass gasification; alumina-forming austenitic stainless steel; thermodynamic modelling; kinetic modelling; Kemi; Chemistry;

    Abstract : To reduce the greenhouse effect, the use of renewable fuel has to be increased. As renewable fuel has different characteristics compared to fossil fuel regarding content of trace metals, alkali, chlorine and sulphur, the corrosion characteristics in high temperature energy processes have to be evaluated.

  6. 4. Alkali-enhanced gasification of biomass : laboratory-scale experimental studies

    Author : Albert Bach-Oller; Kentaro Umeki; Viktor Scherer; Luleå tekniska universitet; []
    Keywords : 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
