摘　　要：在Aspen plus平台上对日产1 kg乙醇的纤维素乙醇微型工厂流程建立流程模拟模型,并构建了完整的生物质组分物性数据库;对微型工厂流程进行了基于微型工厂实验数据和严格热力学模型基础上的物料衡算和能耗计算,并进行了水分回收分析和综合能耗折算。结果表明:在纤维素乙醇微型工厂最大生产能力下,用玉米秸秆生产1 kg纤维乙醇的水用量2.595 7 kg,蒸汽用量3.605 4 kg,废水量8.061 6 kg,均低于目前工艺水平下的玉米淀粉生产乙醇的水用量和废水量;1 kg乙醇消耗各种形式能量36.515 2 MJ,产出能量为53.574 9 MJ,能量产出大于能量投入;1 kg乙醇的综合能耗折合1.826 9 kg标准煤,加工过程中的产出能量折合1.828 0 kg标准煤,能量投入和能量产出基本平衡。The flowsheet simulation raodel of the cellulosic ethanol mini-plant with the capacity of 1 kg/d ethanol production from corn stover and the physical property database were developed on the Aspen plus platform. The mass balance and energy balance of the mini-plant process were calculated and the results show that, producing 1 kg cellulosic ethanol required 2. 595 7 kg fresh water and 3. 605 4 kg stream, 8. 061 6 kg waste water under the maximum productivity of the cellulosic ethanol mini-plant, which was lower than the consumption of the corn based ethanol process; required energy input 36. 515 2 MJ and generated 53. 574 9 MJ, which means that the energy generation was greater than the energy consumption; the integrated energy consumption was 1. 826 9 kg standard coal, while the energy generation during this process was 1. 828 0 kg standard coal, which suggested that there was an energy balance between the output and the input.
