Abstract
The progress of the conversion, the yield, the structure
and the morphology of the produced carbonaceous materials
as a function of time were systematically studied with
pyrolysis-GC/FID and FESEM microscope. The conversion of
galactoglucomannan, bleached kraft pulp and TEMPO
oxidized cellulose nanofibrils followed the reaction
route of glucose being slower though with fibrous
material, higher molar mass and viscosity. The conversion
of kraft lignin was minor following completely different
reaction route. Carbonaceous particles of different shape
and size were produced with yields between 23 and 73%
after 4h with being higher for lignin than carbohydrates.
According to the results, potential pulp mill streams
represent lignocellulosic resources for generation of
carbonaceous materials.
