Abstract为考察超低浓度马来酸对玉米芯纤维素的水解性能,该文采用高温液态水预处理和超低马来酸水解相结合的两步法。3,5-二硝基水杨酸(DNS)比色法和高效液相色谱法(HPLC)分析表明,第一步预处理(200℃,10min,4MPa,500r/min,液固比20:1mL/g)玉米芯可获得12.24g/L还原糖,半纤维素转化率91.76%,损失3.61%的纤维素;其残渣进行第二步酸水解(质量分数0.1%,220℃,20min,4MPa,500r/min,液固比20:1mL/g)可获得9.94g/L还原糖,纤维素转化率达95.17%,约1/3转化为糖。气相色谱-质谱联用(GC-MS)分析表明,第二步水解液中含有多种木质素降解副产物,如苯酚、苯甲酸等,带有多种活泼基团,可能与糖降解物反应,加快葡萄糖降解正反应的进行。改进反应器,使得糖降解物和木质素降解物及时排出,可提升马来酸水解性能,为马来酸在生物质水解领域的应用提供参考。
