    • Comparative study on the thermal behavior of untreated and various torrefied bark, stem wood, and stump of Norway spruce 

      Barta-Rajnai, Eszter; Wang, Liang; Sebestyén, Zoltán; Barta, Zsolt; Khalil, Roger Antoine; Skreiberg, Øyvind; Grønli, Morten; Jakab, Emma; Czégény, Zsuzsanna (Journal article; Peer reviewed, 2017)
      In this work, the torrefaction of different parts of Norway spruce (stem wood, bark, and stump) was studied. Three different torrefaction temperatures were applied: 225, 275, and 300 °C with 30 and 60 min isothermal periods. ...

    • Comprehensive Compositional Study of Torrefied Wood and Herbaceous Materials by Chemical Analysis and Thermoanalytical Methods 

      Barta-Rajnai, Eszter; Jakab, Emma; Sebestyén, Zoltán; May, Zoltán; Barta, Zsolt; Wang, Liang; Skreiberg, Øyvind; Grønli, Morten; Bozi, Janos; Czégény, Zsuzsanna (Journal article; Peer reviewed, 2016)
      In this work, the torrefaction of three biomass materials, black locust wood, wheat, and rape straw, was studied at various temperatures: 200, 225, 250, 275, and 300 °C. The thermal stability and formation of the decomposition ...

    • Effect of Temperature and Duration of Torrefaction on the Thermal Behavior of Stem Wood, Bark, and Stump of Spruce 

      Barta-Rajnai, Eszter; Wang, Liang; Sebestyén, Zoltán; Barta, Zsolt; Khalil, Roger Antoine; Skreiberg, Øyvind; Grønli, Morten; Jakab, Emma; Czégény, Zsuzsanna (Journal article; Peer reviewed, 2017)
      In this work the torrefaction of different parts of Norway spruce (stem wood, bark, and stump) was studied. Three different torrefaction temperatures were applied: 225, 275, and 300 °C with 30 and 60 minutes isothermal ...

    • Effect of torrefaction on physiochemical characteristics and grindability of stem wood, stump and bark 

      Wang, Liang; Barta-Rajnai, Eszter; Skreiberg, Øyvind; Khalil, Roger Antoine; Czégény, Zsuzsanna; Jakab, Emma; Barta, Zsolt; Grønli, Morten (Journal article; Peer reviewed, 2017)
      In this work, Norway spruce stem wood, stump and bark were torrefied in a bench scale tubular reactor at 225, 275 and 300 °C with two residence times (30 and 60 min). Effect of torrefaction on general properties, chemical ...

    • Impact of Torrefaction on Woody Biomass Properties 

      Wang, Liang; Barta-Rajnai, Eszter; Skreiberg, Øyvind; Khalil, Roger Antoine; Czégény, Zsuzsanna; Jakab, Emma; Barta, Zsolt; Grønli, Morten (Journal article; Peer reviewed, 2017)
      In this work, Norway spruce stem wood, stump and bark were torrefied in a tubular reactor. The effects of feedstock type and torrefaction process parameters such as torrefaction temperature and residence time on the ...
