A kinetic study on simultaneously boosting the mass and fixed-carbon yield of charcoal production via atmospheric carbonization
Biocarbon production and utilization
Ash fusion characteristics of spruce stem wood and blends with bark, forest residue and fermentation residues
Comparative study on the thermal behavior of untreated and various torrefied bark, stem wood, and stump of Norway spruce
Fast hydrothermal liquefaction of native and torrefied wood
The work presented in this paper aimed to examine the effect of heating rate on the bio-crude yield of wood hydrothermal liquefaction. Three different heating methods were developed, resulting in heating rates ranging from 66 °C/min to 179 °C/min. The experiments were conducted using Norway spruce w...
CO2 Gasification of Charcoals in the Context of Metallurgical Application
The CO2 gasification reactivity of Norwegian spruce charcoals from stem wood and its forest residue produced at different pressures was investigated in the present study. The gasification behavior was analyzed thermogravimetrically at different gasification temperatures of 800, 850 and 950oC, follow...
Simultaneously boosting the mass and fixed-carbon yields of charcoal from forest residue via atmospheric carbonization
The carbonization of various forest residues in comparison with their stem wood was studied by means of thermogravimetric analyzer operated non-isothermally at atmospheric pressure with a heating rate of 10K/min and a final temperature of 800 °C. GROT (tops and branches) and stem wood samples of Nor...
Biomass Charcoal Properties Changes during Storage
In this work, effects of storage time and conditions on the properties of one woody charcoal were studied. Prior to the storage test, the untreated charcoal was characterized by thermogravimetry/mass spectrometry (TG/MS). Weight loss (TG) and evolution profile curves of selected gaseous products wer...
Effect of Temperature and Duration of Torrefaction on the Thermal Behavior of Stem Wood, Bark, and Stump of Spruce
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 periods. The untreated and torrefied biomass materials were characterized by ther...
