摘 要：
[目的]初步研究甘蔗渣最佳超/亚临界水解液化反应条件和糠醛的分离。[方法]以甘蔗渣为原料,考察了反应温度、固液比(甘蔗渣/水)对还原糖浓度和糠醛百分含量的影响,以及温度对糠醛分离的影响。[结果]反应温度为368℃,固液比为1∶7.9为甘蔗渣最佳的产糖条件,且产生的糠醛少。在较高的温度下(>300℃)产生的糠醛较少。通过放气排出反应中产生的糠醛,第1个放气点排出的糠醛最多,放气效果最好。[结论]对于放气排出的混合液体,应该进一步研究分离其中的有用成分糠醛,实现秸秆资源的更好利用。

摘 要：
[Objective] The research aimed to initially study the best super/sub-critical liquefaction reaction condition of bagasse and the separation of furfural.[Method] The bagasse was as the material,the influences of reaction temperature and solid-liquid ratio(bagasse/water) on the reducing sugar concentration and the percentage content of furfural were inspected.Moreover,the influence of temperature on the furfural separation was also inspected.[Result] The best sugar production condition of bagasse was that the reaction temperature was 368 ℃,and the solid-liquid ratio was 1∶7.9.Under the best condition,the furfural was less.At the high temperature(>300 ℃),the generated furfural was less.Via the deflation,the generated furfural in the reaction was discharged.The discharged furfural at the first deflation point was the most,and the deflation effect was the best.[Conclusion] For the discharged mixed liquid,the useful furfural should be further studied and separated,which realized the better utilization of straw resource.
