| 摘 要： | 为了提高稻草(RS)的转化率和产物收率,采用了超声、蒸汽爆破和Na_2SO_3处理3种方法对稻草进行预处理(处理后的稻草分别记为CS-RS、ZQ-RS和Na_2SO_3-RS),通过XRD、SEM、元素分析及化学组分含量分析,筛选出Na_2SO_3处理是最好的预处理方法。Na_2SO_3-RS在200℃下经10%Fe-resin在3.3%的NaCl溶液中水解后,转化率达到97.3%,还原糖(TRS)和平台化合物乙酰丙酸(LA)的产率分别达到为29.6%和13.5%。

| Abstract: | To increase the conversion of rice straw(RS) and the yield of products,we employed three methods,which were ultrasonic wave,steam explosion and Na2SO3 pretreatment to pretreat RS (the treated RS noted as CS-RS,ZQ-RS and Na2SO3-RS,respectively) and found that Na2SO3 treatment was the best pretreatment method based on XRD,SEM,elemental analysis and content of cellulose,hemicellulose and lignin.The conversion of Na2SO3-RS and the yield of total reducing sugar(TRS) and levulinic acid(LA) were 97.3％,29.6％ and 13.5％,respectively by 10％ Fe-resin in 3.3％ NaCl solution under 200 ℃. |
