| 摘要: |
| 秸秆的化学成分复杂,主要由纤维素、半纤维素和木质素三大部分组成。经过预处理、发酵和脱水可生成燃料乙醇,秸秆乙醇化技术已经备受关注。针对预处理、发酵和脱水3个过程的多种化学或生物技术的研究进展进行了分析,同时也指出其不足。秸秆预处理中的超临界技术虽然设备制造成本高,但在秸秆资源化中与传统技术相比显示了独特的优势,具有反应迅速、无需催化剂、无产物抑制等优点。 |

| Abstract: |
| In the current circumstances of energy shortage,the straw,abundant and renewable resources,has great development potential.Straw ethanol production technology has caused widespread concern.Ethanol can be obtained by pretreatment,fermentation and dehydration of straw.At present,a variety of chemical or biological technologies have been carried out for these three processes,and to be successful.This paper outlined the technical progress in these processes,but also pointed out the shortcomings of some technical.At pretreatment,the supercritical technology in the resourcilization technologies of straw demonstrates the unique advantages over traditional technologies,such as not requiring additional catalyst,much higher reaction rate,and no inhibitory reaction of product.However there are still some difficulties. |
