The objective of this study was to analyze the structure property of the solid residues and the category of liquid products from wheat straw after depolymerization with sulfuric acid. The results showed that the structure of wheat straw after depolymerization was destroyed to a certain extent
most of hemicellulose was effective removal
but its crystallinity was still high. Product types of wheat straw after depolymerization were quite different and were affected by several factors
including reaction time
temperature and acid concentration and other factors. The major products in liquid of the depolymerized wheat straw were glucose
xylose
arabinose
acetic acid
furfural
and 5-hydroxymethyl furfural. By studying the interactions between the H+ and the structure of hemicellulose
cellulose and lignin
the formation mechanism of products after deploymerization wheat straw with sulfuric acid were proposed.
