In this study, we measured changes in the lignin content of acidified lignocellulosic biomass such as rice straw, saw dust, chestnut shell and peanut hull and analyzed the conversion property to cellulosic ethanol. It turns out that the lignin content increases in chestnut shell, rice straw, saw dust, peanut hull order and the conversion property to cellulosic ethanol is superior in the reverse order. Thus, the removal of lignin by acidification is necessary. In addition, as the concentration of sulfuric acid increases, the lignin content decreases and the yield of cellulosic ethanol increased. The optimum concentration of sulfuric acid is 20 wt%.
