The environmental conditions generated by the consumption of fossil fuels have created a growing interest in alternative energy sources for various sectors of society. In the case of the aviation sector, one solution is biojet fuel as a sustainable fuel for direct application in flights. The alcohol to jet (ATJ) fuel process has high expectations due to its performance and for revalorizing alcohols from fermentation. Starting from ethanol, the ATJ process consists of four stages: dehydration, oligomerization, hydrogenation, and separation. On the other hand, process intensification philosophy promotes process efficiency, reducing the number of equipment used, reducing land use, and combining different phenomenologies. In this sense, this work researches the outlines of implementing intensification ideas to the ATJ process using reactive distillation (RD) to improve the sustainable performance of jet fuel production. Particularly, the oligomerization and hydrogenation stages will be subject to process intensification strategies. Both strategies were evaluated considering various sustainability indicators (global warming potential, mass intensity, energy intensity, economic impact, etc.). The most intensified alternative presented is an RD column with two reactive sections. Once a distillation column with two reactive zones was implemented, an improvement in the return on investment value of close to 50% and a decrease in the total annual cost of close to 90% were observed. The global warming potential value improved by 70%. Likewise, an improvement of close to 30% was observed in efficiency, mass intensity, and thermodynamic efficiency.

强化生物喷气燃料生产的低聚和加氢阶段：初步概述
化石燃料消耗造成的环境条件已引起社会各部门对替代能源的兴趣日益增长。就航空部门而言，一种解决方案是将生物喷气燃料作为直接应用于飞行的可持续燃料。酒精转化为喷气燃料 (ATJ) 燃料工艺因其性能和发酵产生的酒精的再价值而受到很高的期望。ATJ 工艺以乙醇为原料，包括四个阶段：脱水、低聚、氢化和分离。另一方面，过程集约化理念提高了过程效率，减少了使用的设备数量，减少了土地使用，并结合了不同的现象。在这个意义上说，这项工作研究了使用反应蒸馏 (RD) 对 ATJ 工艺实施强化理念的概要，以提高喷气燃料生产的可持续性能。特别是，低聚和氢化阶段将受到过程强化策略的影响。考虑到各种可持续性指标（全球变暖潜能值、质量强度、能源强度、经济影响等），对这两种策略进行了评估。提出的最强化的替代方案是具有两个反应部分的 RD 塔。实施具有两个反应区的蒸馏塔后，观察到投资回报率提高了近 50%，年度总成本降低了近 90%。全球变暖潜能值提高了 70%。同样地，
