One solution to the supply chain challenges of cellulosic biofuels is a network of local biomass processing depots (LBPDs) that can produce stable, dense, intermediate commodities and valuable co-products prior to shipping to a refinery. A techno-economic model of an LBPD facility that could incorporate multiple technologies and products was developed in Microsoft Excel to be used to economically and environmentally evaluate potential LBPD systems. In this study, three technologies (ammonia fiber expansion or AFEX™ pretreatment, fast pyrolysis, and leaf protein processing) were assessed for profitability. Pyrolysis was slightly profitable under the base conditions, leaf protein processing was highly unprofitable, and AFEX was profitable if biomass drying was not required. This model can be adapted to multiple feedstocks and end uses, including both economic and environmental modeling.
解决纤维素生物燃料供应链挑战的一种方案是建立一个本地生物质加工站（LBPD）网络，这些加工站可以在将稳定、密集的中间商品和有价值的副产物运往精炼厂之前进行生产。在 Microsoft Excel 中开发了一种 LBPD 设施的技术经济模型，可以结合多种技术和产品，用于经济和环境评估潜在的 LBPD 系统。在这项研究中，评估了三种技术（氨纤维膨胀或 AFEX™预处理、快速热解和叶蛋白加工）的盈利能力。在基础条件下，热解略有盈利，叶蛋白加工极不盈利，如果不需要生物质干燥，则 AFEX 盈利。该模型可以适应多种原料和最终用途，包括经济和环境建模。
