Renewable aviation fuel is the most promising alternative to achieve the sustainable recovery of aviation sector. The production of this biofuel is technically feasible, but its economic competitiveness is still a challenge in spite of the use of low-cost raw materials as well as strategies for energy reduction. In this context, the biorefineries are an alternative that improves the profitability. Thus, in this work the conversion of waste cooking oil (WCO) through a biorefinery scheme is proposed along with the intensification of the biojet fuel separation zone. The resulting biorefinery produce 306.4 kg/h of biojet fuel, and it is self-sufficient in electricity requirements. The intensified biorefinery reduces in 66.95% the energy consumption, respect to the conventional one, along with a reduction of 3.07% in CO₂ emissions. The intensified biorefinery has a capital cost 11.74% higher than the conventional one, but 2.68% and 8.13% less operating costs for steam and cooling water, respectively. The intensified biorefinery scheme can be improved through energy integration and the intensification of the ethanol recovery train. Finally, the conversion of WCO through an intensified biorefinery allows generating biofuels, bioenergy, and value-added products, with the simultaneous revaluation of this hazardous residue.

可再生航空燃料是实现航空业可持续复苏的最有希望的替代品。这种生物燃料的生产在技术上是可行的，但尽管使用了低成本原材料以及节能策略，但其经济竞争力仍然是一个挑战。在这种情况下，生物精炼厂是提高盈利能力的替代方案。因此，在这项工作中，提出了通过生物精炼方案对废弃食用油 (WCO) 进行转化以及生物喷气燃料分离区的强化。由此产生的生物精炼厂生产 306.4 公斤/小时的生物喷气燃料，并且在电力需求方面是自给自足的。相对于传统的强化生物精炼厂减少了 66.95% 的能源消耗，同时减少了 3.07% 的 CO ₂排放。强化生物精炼厂的资本成本比传统精炼厂高 11.74%，但蒸汽和冷却水的运营成本分别降低 2.68% 和 8.13%。强化生物精炼方案可以通过能源整合和乙醇回收流程的强化来改进。最后，通过强化生物精炼厂转化 WCO 可以生产生物燃料、生物能源和增值产品，同时对这种有害残留物进行重新估价。
