This paper addresses the techno-economic evaluation and optimisation of processes converting lignocellulosic biomass into liquid fuels, through the development of a suitable framework and the modelling and design of Biomass to Liquids (BTL) processes. In particular, the focus is on the production of drop-in fuels through gasification and Fischer–Tropsch (FT) synthesis. Several conversion technologies are presented and evaluated in the literature, but the comparison of different options is hazardous because of the different assumptions and methodologies adopted in each study. A systematic and consistent approach is therefore developed to explore the trade-offs of alternative process configurations and of the operating conditions. The comparison presented in this study explores the trade-offs of different technological options in terms of competing economic and thermodynamic objectives. Results show that for 200 MW_th biomass input plant capacities, production costs are in the range of 1.0–1.4 € l⁻¹ for technologies producing up to about 0.5 kJ_FT kJ_th⁻¹ and close to being neutral in terms of electricity balance. For technologies using electrolysis the conversion can increase to 0.8 kJ_FT kJ_th⁻¹ with production costs of 1.8 € l⁻¹. The electricity storage capacity, in this case, is of 0.5 kJ_e kJ_FT⁻¹, corresponding to a net electricity requirement of about 0.4 kJ_e kJ_th⁻¹.

木质纤维素生物质转化为费-托燃料的热经济分析和多目标优化†

本文通过开发合适的框架以及生物质到液体（BTL）过程的建模和设计，致力于技术经济评估和将木质纤维素生物质转化为液体燃料的过程的优化。特别是，重点是通过气化和费-托合成技术生产直接燃料。文献中介绍并评估了几种转换技术，但是由于每个研究采用的假设和方法不同，因此比较不同的选择非常危险。因此，开发了一种系统且一致的方法来探索替代工艺配置和操作条件之间的权衡。本研究中提出的比较从竞争的经济和热力学目标出发，探索了不同技术选择之间的权衡。结果表明，对于200 MW_对于生物质输入工厂的能力，对于生产最高约0.5 kJ_FT kJ_th^-1的技术，生产成本在1.0–1.4€l^-1的范围内，并且在电力平衡方面接近中性。对于使用电解的技术，转化率可以提高到0.8 kJ_FT kJ_th^-1，生产成本为1.8€l^-1。在这种情况下，蓄电容量为0.5kJ_e kJ_FT^-1，对应于约0.4kJ_e kJ_th^-1的净电力需求。
