This study assesses the environmental potential of crop residues and the techno‐economic potential of biojet fuel (BJF) production in Brazil. Different production routes are evaluated from two types of biomass residues (sugarcane straw and eucalyptus harvest residue), and four different technological pathways (alcohol to jet, Fischer–Tropsch, hydrothermal liquefaction and pyrolysis). The environmental potential of biomass residues is determined utilizing spatio‐temporal projections of land‐use change in Brazil and by explicitly modeling the erosion risk and the soil organic carbon (SOC) balance spatially. The assessment of the techno‐economic potential of BJF production from the environmental potential of sugarcane straw (SCS) and eucalyptus harvest residues (EHRs) considers the BJF total costs, which result from a summation of biomass residue recovery costs, BJF conversion costs, and BJF transportation costs. These BJF total costs are compared with the range of fossil jet fuel prices at Brazilian airports to quantify the techno‐economic potential. The environmental potential of biomass residues varies from 70 Mt in 2015 to 102 Mt in 2030, with SCS being highly constrained by SOC, whereas EHRs are more constrained by the high erosion risk. These quantities can generate a techno‐economic BJF potential ranging from 0.45 EJ in 2015 (46 US$/GJ – 65 US$/GJ) to 0.67 EJ in 2030 (19 US$/GJ – 65 US$/GJ). In 2030, several BJF production routes can be competitive with fossil jet fuel prices. The northeast and southeast regions have the highest potential, especially in 2030. © 2020 The Authors.

绘制巴西生物质残渣生产生物喷气燃料的环境和技术经济潜力

这项研究评估了巴西农作物残渣的环境潜力和生物喷气燃料（BJF）生产的技术经济潜力。从两种类型的生物质残余物（甘蔗秸秆和桉树收获残余物）以及四种不同的技术途径（从酒到喷射，费托，水热液化和热解）评估了不同的生产途径。利用巴西土地利用变化的时空预测，并通过在空间上明确建模侵蚀风险和土壤有机碳（SOC）的平衡，可以确定生物质残余物的环境潜力。从甘蔗秸秆（SCS）和桉树收获残余物（EHRs）的环境潜力评估BJF生产的技术经济潜力考虑了BJF的总成本，这是由生物质残渣回收成本，BJF转换成本和BJF运输成本的总和得出的。将这些BJF的总成本与巴西机场的化石航空燃料价格范围进行比较，以量化技术经济潜力。生物质残留物的环境潜力从2015年的70 Mt到2030年的102 Mt不等，其中SCS受SOC的高度限制，而EHR受较高的侵蚀风险的限制。这些数量可以产生技术经济的BJF潜力，范围从2015年的0.45 EJ（46美元/ GJ – 65美元/ GJ）到2030年的0.67 EJ（19 US $ / GJ – 65 USD / GJ）。到2030年，BJF的几条生产路线可与化石喷气燃料价格竞争。东北和东南地区的潜力最大，尤其是在2030年。©2020作者。生物燃料，生物制品，
