TL;DR: In this article, a pathway of cellulose pyrolysis via anhydromonosaccharide is proposed including polymerization to polysaccharides (a reversible reaction) as a key reaction to carbonized product formation.
Abstract: 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.

TL;DR: In this article, the activation energy of xylan, cellulose, and eight lignocellulosic biomass samples (including corn stover, cotton stalk, palm oil husk, pine wood, red oak, sugarcane bagasse, switchgrass, and wheat straw) were measured in a TA SDT Q600 thermogravimetric analyzer.

TL;DR: In this paper, the influence of pyrolysis temperature (300-800°C) on composition and surface chemistry of biochar was investigated and the results showed that fixed C, ash and basic cations of BC increased while its moisture, volatiles and elemental composition (O, H, N and S) decreased with increasing pyrolysis temperature.

TL;DR: In this article, the effectiveness of biochar produced from three different biomass species such as wheat straw, timothy grass and pinewood was estimated through two different conversion scenarios: slow heating rate (SHR) and high heating rate pyrolysis.

TL;DR: In this article, a detailed study of all the pyrolysis products was made, and the results of this study were compared with previous data for lignins, degraded lignin, polysaccharides, peptides and lipids, and showed that the hymatomelanic acid fraction represents mainly lipid materials.
