木质纤维生产燃料酒精已成为一个热门研究课题,预处理技术作为木质纤维转化为能源的关键步骤,也成为科研工作者关注的焦点。传统的化学处理、机械处理技术等耗能较多,且不同程度地存在环境污染;蒸汽爆破具有处理时间短、减少化学药品用量、无污染、能耗低等优点,是很有发展前途的预处理新技术;生物处理技术从成本和设备角度考虑,占有独特的优势,但处理效率较低,利用基因工程和传统的生物技术对菌种和酶进行改造,提高酶活力,降低酶成本,也有望应用于大规模工业生产;利用多种预处理方法相结合,开发更加高效、无污染且成本低的预处理手段,将是今后木质纤维原料预处理的发展趋势。木质纤维原料预处理问题的解决,将为今后以木质纤维为原料的燃料酒精工业化生产打下坚实的基础。
