生物炼制是多产品系统的一个例子，它将生物质转化过程和设备集成在一起，从生物质中生产燃料、电力和化学品。本研究着重于木质纤维素原料（LCF）生物精炼生产乙醇，琥珀酸，乙酸和电力的技术设计，经济和环境分析。由于琥珀酸及其衍生物的全球潜在需求量可达每年3000万吨，如果生产成本和市场价格大幅降低，琥珀酸是一种有前途的高价值产品。经济分析结果表明，与单产乙醇装置相比，设计的炼油厂具有很大的潜力，即使丁二酸价格降低或基建投资增加一倍。在生态效率方面，由于酸发酵过程中固定了CO2，LCF生物精炼厂表现出更好的环境绩效，主要是在全球变暖潜力方面。对生态效率的总体评价取决于对每个影响类别的重视程度。(C)2009爱思唯尔有限公司版权所有。
Biorefinery, an example of a multiple products system, integrates biomass conversion processes and equipment to produce fuels, power and chemicals from biomass. This study focuses on technical design, economic and environmental analysis of a lignocellulosic feedstock (LCF) biorefinery producing ethanol, succinic acid, acetic acid and electricity. As the potential worldwide demand of succinic acid and its derivatives can reach 30 million tons per year, succinic acid is a promising high-value product if production cost and market price are substantially lowered. The results of the economic analysis show that the designed refinery has great potentials compared to the single-output ethanol plant; even when the price of succinic acid is lowered or the capital investment doubled. In terms of eco-efficiency, the LCF biorefinery shows better environmental performances mainly in global warming potential due to CO2 fixation during acid fermentation. The overall evaluation of the eco-efficiency depends on the importance attached to each impact category. (C) 2009 Elsevier Ltd. All rights reserved.
