| 摘 要： | 采用氨水预处理的单因素与正交试验,研究氨水浓度、时间、温度、基质浓度和粒径对玉米秸秆糖化预处理的影响.结果表明:影响氨预处理玉米秸秆的还原糖得率的主要因素是粒径,而影响木质素去除率的主要因素是氨水浓度、浸泡时间和浸泡温度,其最优工艺条件为氨水浓度15％,时间39 h,温度40℃,基质浓度162.5 g·L-1,粒径0.... |

| Abstract: | The effects of ammonia concentration,processing time,temperature,substrate concentration,and stalk diameter by ammonia-pretreatment on the saccharification of corn stalks using single factor design and orthogonal design were investigated.The results indicated that the main effect factor on the reducing sugar yield was corn stalks size and the main effect factors on the lignin removal rate was ammonia concentration,time and temperature.The optimum conditions were ammonia concentration 15%,time is 39 h,temper... |
| Keywords: | corn stalks ammonia reducing sugar yield lignin removal rate |
