摘要：

Pyrolysis behavior of levoglucosan (1,6-anhydro-beta-D-glucopyranose), the major anhydromonosaccharide formed during cellulose pyrolysis, was studied at 250degrees 400 degreesC 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.
