    • CO2 Gasification of Chars Prepared by Fast and Slow Pyrolysis from Wood and Forest Residue: A Kinetic Study 

      Wang, Liang; Li, Tian; Várhegyi, Gábor; Skreiberg, Øyvind; Løvås, Terese (Journal article; Peer reviewed, 2017)
      The CO2 gasification of chars was investigated by thermogravimetric analysis (TGA). The chars were prepared from spruce and its forest residue. Prior to the gasification, the raw materials were pelletized and pulverized. ...

    • EFFECT OF STORAGE TIME AND CONDITIONS ON BIOMASS CHARCOAL PROPERTIES 

      Wang, Liang; Hu, Kathryn; Higashi, Charissa; Skreiberg, Øyvind; Myrvågnes, Viktor; Grønli, Morten; Antal, Michael Jerry; Várhegyi, Gábor (Journal article; Peer reviewed, 2015)
      In this work, effects of storage time and conditions on the properties of one woody charcoal were studied. Analyses results showed that the volatile matter content of the charcoal samples collected from the bottom section ...

    • Thermal Decomposition Kinetics of Wood and Bark and their Torrefied Products 

      Barta-Rajnai, Eszter; Várhegyi, Gábor; Wang, Liang; Skreiberg, Øyvind; Grønli, Morten; Czégény, Zsuzsanna (Journal article; Peer reviewed, 2017)
      The pyrolysis kinetics of Norway spruce, its bark, and their torrefied products was studied. Thermogravimetry (TGA) was employed with linear and stepwise heating programs. Altogether 36 TGA experiments were evaluated ...
