  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. Fundamental Studies on Direct Chromium Alloying by Chromite Ore with Designed Alloying Precursor
