超临界下有机酸对稻秆水解糖化的影响
Effects of organic acids on rice straw on supercritical hydrolysis
摘要
Abstract
With the organic acids ( formic acid, acetic acid, and propionic acid) as the catalyst, hydrolysis saccharification of rice straw in the batch reactor was investigated under the condition of the super- and sub-critical water. The reaction temperature, reaction time and solid-to-liquid ratio for reduction sugar yield were studied. Results showed that organic acid was helpful to the hydrolysis saccharification of straw. Reducing sugar yield could increase when adding organic acid. This trend was most evident when adding formic acid. With the extension of reaction time, reducing sugar yield could gradually decreased. In the appropriate range, reducing sugar production was much higher with the increasing of the solid-liquid ratio. The best conditions on straw hydrolysis saccharification in supercritical water from the experiment were as follows; formic acid concentration 3%, solid-to-liquid ratio 4:60, temperature 410 ℃ , and the reaction time 5 min. Under the conditions, the reducing sugar production reached the highest, 6. 65 g/L.关键词
