It is found that cellulose with higher crystallinity produces higher yield of levoglucosan. Specifically, Celluloses II and III exhibit lower crystallinity index and levoglucosan (LG) yield as compared to Cellulose I and IV. Notably, despite Cellulose IV having a higher crystallinity index than Cellulose I, the differences in crystalline structure and hydroxyl group level lead to a lower levoglucosan yield in pyrolysis. Thermogravimetric kinetics analysis suggests that cellulose with high crystallinity yields more anhydro-sugars through dehydration reactions. Whereas amorphous cellulose predominantly produces lower molecular weight molecules through ring scission reactions. It is found that Cellulose II yields the maximum amount of glucose, while higher crystallinity levels have a negative impact on the sugar yield in general.<\/p>\n<p style=\"text-align: justify;\">Related results were published in Industrial Crops &amp; Products:<\/p>\n<p style=\"text-align: justify;\">HL Ma, FX Xu, YC Zhang, MJ Huang, MF Li, GH Wang, MX Huang, <strong>Zhen Fang*, <\/strong>LQ Jiang*, Non-unified effects of cellulose allomorphs on fast pyrolysis and enzymatic hydrolysis, Industrial Crops and Products.
