Abstract The Fischer-Tropsch process is less complex and more environmentally friendly alternative to petroleum-based fuels. With growing interest in biomass-to-fuel conversion like the production of bioethanol, there is a steady supply of unfermentable biomass from bioethanol industries, which can be gasified and converted to Fischer-Tropsch syncrude. In this work, the economic and ecological feasibility of integrating a Fischer-Tropsch process using syngas obtained from the gasification of dry distillers’ grain is explored. Data from a lab-scale experiment using pelletized promoted iron supported on Carbon Nano Tubes (Fe/CNT) is used to simulate a plant for the production of 1000 kg of syncrude/h. The techno-economic feasibility of setting up a Fischer-Tropsch process is explored based on chemical engineering plant cost index of 628.2. An internal rate of return of 107.9% was obtained with a net annual profit of 5.2 MUSD/year which is higher than those reported for other Fischer-Tropsch plants due to the readily availability of the feedstock without any associated transportation costs. The potential environmental impact of the Fischer-Tropsch fuels was evaluated by the WAste Reduction (WAR) algorithm and suggested that the integration of the Fischer-Tropsch process into the bio-ethanol production plant is environmentally benign.

乙醇工业中用于生物柴油和生物汽油生产的综合费托工艺的技术经济和生命周期评估

摘要 Fischer-Tropsch 工艺比石油基燃料更简单、更环保。随着人们对生物乙醇生产等生物质向燃料转化的兴趣日益浓厚，生物乙醇行业可以稳定供应不可发酵的生物质，这些生物质可以气化并转化为费托合成原油。在这项工作中，探索了使用从干酒糟气化中获得的合成气整合费托工艺的经济和生态可行性。使用负载在碳纳米管 (Fe/CNT) 上的丸状促进铁进行的实验室规模实验的数据用于模拟工厂，以每小时生产 1000 公斤的合成粗铁矿为原料。 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 基于 628.2 的化工设备成本指数，探索了建立费托工艺的技术经济可行性。内部回报率为 107.9%，年净利润为 5.2 MUSD/年，高于其他费托工厂报告的利润，因为原料易于获得，无需任何相关的运输成本。Fischer-Tropsch 燃料的潜在环境影响通过减少废物 (WAR) 算法进行评估，并表明将 Fischer-Tropsch 过程集成到生物乙醇生产工厂中是对环境无害的。
