In the current aviation market context, the search for more sustainable and low-carbon emission alternatives has been driving the demand for biojet fuel. In this context, this study aimed to assess the feasibility of a biojet fuel production plant in Brazil using the Alcohol-to-Jet technology with ethanol as raw material. The process was simulated in Aspen Plus® v12.1 and the results were applied in an economic analysis. The biojet fuel and ethanol breakeven prices were determined in different scenarios. In the best scenario, biojet fuel would cost US$ 1.86 per kg, which is 31% less than the average-priced sustainable aviation fuel marketed in the United States. It was also demonstrated that the process would be economically viable in the country − for substitution of conventional aviation fuel at competitive market values − if there was a 44–55% reduction in the ethanol price, which seems feasible if one considers the pre-COVID-19 pandemic levels. The obtained results indicate this process technology as an important alternative to be considered in future policies, and serve as a basis for future works, being easily adapted for other economic contexts if necessary.

巴西可持续航空燃料酒精到喷气机生产的工艺模拟和经济评估


在当前的航空市场背景下，寻找更可持续和低碳排放替代品一直在推动对生物喷气燃料的需求。在此背景下，本研究旨在评估巴西生物喷气燃料生产厂使用以乙醇为原料的酒精制喷气技术的可行性。该过程在 Aspen Plus® v12.1 中进行模拟，并将结果应用于经济分析。生物喷气燃料和乙醇盈亏平衡价格是在不同情况下确定的。在最好的情况下，生物喷气燃料的成本为每公斤 1.86 美元，比美国市场上销售的可持续航空燃料的平均价格低 31%。它还证明，如果乙醇价格下降 44-55%，则该过程在该国经济上是可行的 - 以具有竞争力的市场价格替代传统航空燃料 - 如果考虑到新冠疫情之前的情况，这似乎是可行的-19 大流行级别。获得的结果表明，该工艺技术是未来政策中需要考虑的重要替代方案，并作为未来工作的基础，如有必要，可以轻松适应其他经济环境。
