建立了数学规划模型，分析了以木质纤维为原料生产乙醇的经济可行性。乙醇厂的最佳规模取决于原料运输成本的增加和随着工厂规模的扩大而降低的平均工厂成本之间的权衡。乙醇工厂是在假设它利用最新的技术进步进行稀酸水解的基础上建立起来的。潜在的原料包括能源作物、作物残渣和木质生物质。研究发现，最近的技术进步似乎使乙醇与汽油竞争，但前提是将价值更高的化学品作为乙醇的副产品生产。作物残渣的低成本和化学成分使其作为原料具有吸引力。(C)1999爱思唯尔科学有限公司。保留所有权利。
A mathematical programming model is built to analyze the economic feasibility of producing ethanol from lignocellulosic feedstocks. The optimal size of an ethanol plant is determined by the trade-off between increasing transportation costs for feedstocks versus decreasing average plant costs as the plant size increases. The ethanol plant is modeled under the assumption that it utilizes recent technological advancements in dilute acid hydrolysis. Potential feedstocks include energy crops, crop residues and woody biomass. It is found that the recent technological advancements appear to make ethanol competitive with gasoline, but only if higher valued chemicals are produced as co-products with the ethanol. The low cost and chemical composition of crop residues make them attractive as a feedstock. (C) 1999 Elsevier Science Ltd. All rights reserved.
