木质纤维素资源生物精炼技术研究进展

开发利用可再生性的木质纤维素资源来生产液体燃料和大宗化学品,对于解决人类发展面临的资源与环境危机具有重要的意义。然而,作为其代表性工艺的纤维素乙醇生产却因为经济上无法过关而迟迟不能真正实现产业化。采用生物精炼技术,充分利用木质纤维素材料中各种组分,生产包括部分高值产品的多种产品,是克服其转化技术产业化经济可行性问题的有效措施。综述了木质纤维素原料生物精炼技术的研究发展现状,着重阐述了玉米芯的生物精炼技术产业化进展,并对木质纤维素的生物精炼前景进行了展望。

Progress in biorefinery technology of lignocellulosic resoures

Development and utilization of renewable lignocellulosic resources to produce liquid fuels and bulk chemicals, for solving resource and environmental crisis faced by human development, is of great significance. However, as its representative process, cellulosic ethanol production can not realize industrialization because the economy has been not efficient enough yet. Using biorefinery technology, full use of the various components of lignocellulosic materials to produce various products, includ!ng some kinds of products with high-value, is an effective measure to overcome its economic feasibility obstacle of transforming the technology to industry. Research and development status of lignocellulosic feedstock biorefinery technology were overviewed, focusing on the progress of corncob biorefinery technology, and the prospect of lignocellulosic biorefinerv industry was forecasted.
