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 CO(2) fixation during acid fermentation. The overall evaluation of the eco-efficiency depends on the importance attached to each impact category.
生物炼制厂是一种多产品系统的范例，它集成了生物质转化过程和设备，从生物质中生产燃料、电力和化学品。本研究侧重于从木质纤维素原料（LCF）生产乙醇、琥珀酸、乙酸和电力的生物炼制厂的技术设计、经济和环境分析。由于全球对琥珀酸及其衍生物的潜在需求可能达到每年 3000 万吨，如果能大幅降低生产成本和市场价格，琥珀酸将成为一种有前途的高附加值产品。经济分析的结果表明，与单一输出乙醇厂相比，设计的炼油厂具有很大的潜力；即使降低琥珀酸的价格或资本投资增加一倍也是如此。就生态效率而言，LCF 生物炼制厂由于在酸发酵过程中固定 CO(2)，因此在全球变暖潜势方面表现出更好的环境性能。生态效率的综合评价取决于对每个影响类别的重视程度。
