Formed fermentation inhibitors during acid saccharification leads to poor alcohol production based on lignocellulosic bio-alcohol production process. In this work, it is focused on the formation of fermentation inhibitors from xylan, which is influenced by reaction tempearature and time of acidic sacharifiaction of xylose and glucuronic acid. In second step of concentrated acid hydrolysis, part of xylose and glucuronic acid was converted to furfuraldehyde and formic acid by dehydration and rearrangement reactions. Furfural was form from xylose, which was highly sensitive to reaction temperature. Formic acid was come from both xylose and glucuronic acid, which supposed to main inhibitor in biobutanol fermentation. Reaction temperature of second hydrolysis was main variables to control the furfural and formic acid generation. Careful control of acid saccharification can reduce generation of harmful inhibitors, especially second step of concentrated sulfuric acid hydrolysis process.
