这是第一次使用相同的分析方法通过领先的技术对单一来源的纤维素生物质进行预处理，以提供比较性能数据。特别地，应用氨爆炸、氨水再循环、受控pH、稀酸、流通和时间方法来制备玉米秸秆，用于随后通过奥本大学、达特茅斯学院、密歇根州立大学、国家可再生能源实验室、普渡大学和德克萨斯A&M大学之间的应用基础和创新生物质精炼联盟（CAFI）生物转化为糖。农业和工业咨询委员会为该项目提供指导。预处理条件的选择是基于团队对每种技术的丰富经验，并使用标准方法对产生的流体和固体流进行表征。这些数据被用于关闭物料平衡，并估计所有过程的能量平衡。通过控制纤维素酶的供应和液体的发酵性的固体的消化率也进行了评估，并用于指导最佳预处理条件的选择。根据性能数据进行经济评估，以在一致的基础上估计每种预处理成本。通过这种方法，比较数据开发的糖回收半纤维素和纤维素的组合预处理和酶水解操作时，适用于玉米秸秆。本文介绍了该项目的情况，并总结了《生物资源技术》专刊中报道该研究成果的论文共享方法。(c)2005爱思唯尔有限公司保留所有权利。
For the first time, a single source of cellulosic biomass was pretreated by leading technologies using identical analytical methods to provide comparative performance data. In particular, ammonia explosion, aqueous ammonia recycle, controlled pH, dilute acid, flowthrough, and time approaches were applied to prepare corn stover for subsequent biological conversion to sugars through a Biomass Refining Consortium for Applied Fundamentals and Innovation (CAFI) among Auburn University, Dartmouth College, Michigan State University, the National Renewable Energy Laboratory, Purdue University, and Texas A&M University. An Agricultural and Industrial Advisory Board provided guidance to the project. Pretreatment conditions were selected based on the extensive experience of the team with each of the technologies, and the resulting fluid and solid streams were characterized using standard methods. The data were used to close material balances, and energy balances were estimated for all processes. The digestibilities of the solids by a controlled supply of cellulase enzyme and the fermentability of the liquids were also assessed and used to guide selection of optimum pretreatment conditions. Economic assessments were applied based on the performance data to estimate each pretreatment cost on a consistent basis. Through this approach, comparative data were developed on sugar recovery from hemicellulose and cellulose by the combined pretreatment and enzymatic hydrolysis operations when applied to corn stover. This paper introduces the project and summarizes the shared methods for papers reporting results of this research in this special edition of Bioresource Technology. (c) 2005 Elsevier Ltd.
