The aviation industry is one of the fastest growing modes of transportation sector with an expected annual increase rate of 5% in air traffic until 2030. Currently, the aviation industry is responsible for 12% of the CO2 emissions from various modes of transport sectors and it is expected to grow at a 4.1% of compound annual growth rate near future. Therefore, to address the climate change concerns, the Air Transport Action Group has set ambitious goals to stabilize the net CO2 emissions of the aviation sector by developing a carbon-neutral aviation fuel that is considered a promising alternative to reduce greenhouse gas emissions. Thus, this proposal bridges the gap of producing less carbon-intensive sustainable aviation drop-in fuels from agricultural and forestry-derived feedstock along with biogasoline and biodiesel. Several technologies are in practice to produce bio-jet fuels, among them hydroprocessed esters and fatty acids technology are more mature although they has high production costs. Recent studies revealed that hydrotreated depolymerized cellulosic jet technologies such as hydrothermal liquefaction followed by upgrading have shown lower production costs, high yield, and modest capital costs relative to other technologies. Thus, the current proposal will investigate the production of bio-jet fuel via hydrothermal liquefaction followed by biocrude extraction and fractionation, blending and co-processing via catalytic hydrodeoxygenation, catalytic cracking, and isomerization to produce aviation fuels. The main objective of hydrodeoxygenation is to remove the oxygen from the biocrudes and enhance oxidative stability and calorific value. Hydrochar will be used as catalyst support that is produced during the co-hydrothermal liquefaction to develop hydrodeoxygenation catalysts. After investigating the bio-jet fuel production pathway, techno-economic feasibility and environmental impacts will be studied for scale-up and commercialization. The outcomes of this project will offer the best solutions to our industrial partner Tidewater Renewables in developing sustainable aviation fuel production process. Besides, this proposal will enable other Canadian renewable energy companies to improve their profit margin for bio-jet fuel production.

航空业是增长最快的运输方式之一，直到2030年，空中流量的预期增加率为5％。目前，航空业负责各种运输部门的二氧化碳排放量的12％，预计将以复合年增长率的4.1％增长。因此，为了解决气候变化问题，航空运输行动集团通过开发一种被认为是减少温室气体排放的有希望的替代方案，设定了雄心勃勃的目标，以稳定航空部门的净二氧化碳排放。因此，该提议弥合了产生较少的农业和林业衍生原料以及沼气和生物柴油的碳含量较低的可持续航空液燃料的差距。实际上，几种技术生产生物喷射燃料，其中包括氢化酯和脂肪酸技术，尽管它们的生产成本很高，但它们更加成熟。最近的研究表明，水热液化等氢化纤维素喷气技术随后升级，其生产成本，高收益率和适度的资本成本相对于其他技术显示出较低的生产成本。因此，当前的建议将通过水热液化来研究生物喷射燃料的产生，然后通过催化加氢脱氧，催化裂纹以及异构化以及产生航空燃料的异构化，进行生物挑核提取和分馏，混合和共同处理。加氢氧合的主要目的是从生物侵蚀中去除氧气，并增强氧化稳定性和热量值。氢炭将用作共热热液化过程中产生的催化剂载体，以形成氢氧化催化剂。在研究了生物喷射燃料生产途径后，将研究技术经济可行性和环境影响以进行扩展和商业化。该项目的结果将为我们的工业合作伙伴潮水可再生能源提供最佳解决方案，以开发可持续的航空燃料生产过程。此外，该提案将使其他加拿大可再生能源公司能够提高其生物喷射燃料生产的利润率。
