Characterization of liquid products from slow pyrolysis of woody biomass
Wang, Liang; Czégény, Zsuzsanna; Tschentscher, Roman; Skreiberg, Øyvind (Peer reviewed; Journal article, 2022)In the present work, birch and spruce woodchips were pyrolyzed in a fixed bed reactor under different pyrolysis conditions. The effects of pyrolysis temperature and atmosphere (i.e., with and without gas purging) on yield ... -
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) -
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 slow pyrolysis conditions on biocarbon yield and properties: Characterization of the volatiles
Babinszki, Bence; Sebestyén, Zoltán; Jakab, Emma; Kőhalmi, Luca; Bozi, Janos; Várhegyi, Gábor; Wang, Liang; Skreiberg, Øyvind; Czégény, Zsuzsanna (Peer reviewed; Journal article, 2021)Slow pyrolysis of spruce and birch was performed at various heating programs and conditions in a horizontal quartz tube reactor heated by an electric furnace. The effects of feedstock and carbonization conditions on the ... -
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 ... -
