Abstract
<p>In our previous study, 5-hydroxymethylfurfural (5-HMF) was proposed as a key intermediate in cellulose carbonization. In this study, the formation mechanism of benzene rings in cellulose char was investigated by using 13C-labeled 5-HMFs and 13C-labeled glucoses. Char fraction obtained from the labeled 5-HMFs with glycerol (a model of coexisting primary pyrolysis products of cellulose) or labeled glucoses were analyzed by pyrolysis gas chromatography / mass spectrometry (Py-GC/MS). Based on the 13C content of fragments, the carbonization pathways are proposed, including furan rings partially remaining in the char, direct rearrangement of 5-HMF to phenols, and construction of benzene rings by condensation of the ring-opening fragments of 5-HMF. Based on these results, the mechanism of the char formation from cellulose during pyrolysis is discussed.</p>
