Pyrolysis behavior of levoglucosan as an intermediate in cellulose pyrolysis: polymerization into polysaccharide as a key reaction to carbonized product formation
Open accessAbstract
Pyrolysis behavior of levoglucosan (1,6-anhydro-β-D-glucopyranose), the major anhydromonosaccharide formed during cellulose pyrolysis, was studied at 250°–400°C under nitrogen. The pyrolysis products were found to change stepwise: levoglucosan → MeOH-soluble fraction (lower-molecular-weight products and oligosaccharides) → water-soluble fraction (polysaccharides) → insoluble fraction (carbonized products). From the present experimental results, a pathway of cellulose pyrolysis via anhydromonosaccharide is proposed including polymerization to polysaccharides (a reversible reaction) as a key reaction to carbonized product formation.

The formation of compounds such as levoglucosan and its byproducts results in oxygen functional groups during the pyrolysis.
“The formation of compounds such as levoglucosan (from pyrolysis of cellulose material) and its by products (levoglucosenone, furfural, 2,3butanedione and 5-methylfurfural) results in oxygen functional groups during the pyrolysis (Kawamoto and Saka 2003).”
From Biochar physicochemical properties: pyrolysis temperature and feedstock kind effects (2020) · cites this paper as Kawamoto and Saka 2003
The Introduction says cellulose pyrolysis produces levoglucosan, and Characterization of the products identifies all four listed compounds as products of levoglucosan degradation. That section also detects carbonyl groups in insoluble carbonized products, but it does not say that formation of levoglucosan or the listed byproducts causes those oxygen functional groups.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
