摘要

从石油来源生产的传统喷气燃料造成温室气体排放和空气污染，对人类健康和气候产生负面影响。几项研究表明，从种子和非种子油（棕榈油、菜籽油、向日葵油、卡拉尼亚油、亚麻荠油和麻疯树油）、废食用油、回收猪肉脂肪和城市垃圾等原料中提取的可持续航空燃料（SAF）有可能取代化石喷气燃料。这些可再生燃料由自然资源制成，有助于减少温室气体排放。这项研究回顾了2017年至2025年2月期间进行的研究。作为对比分析，研究了可再生燃料和化石燃料的物理化学特性：密度、粘度、热值、表面张力、冻结和闪点。本对比研究评估了SAF和JET A-1燃料的燃烧特性，重点研究了烟点、点火延迟、点火温度、火焰温度和放热速率等参数。本文介绍了燃烧可持续和化石航空燃料所产生的气体（CO2， CO， SOx和NOx）和颗粒排放。这项研究提高了对可再生燃料特性和质量的理解，支持了可持续燃料替代品的发展。符合ASTM D1655-23和ASTM D7566-23b标准对于接受SAF作为航空运输中可行的能源至关重要。该研究还描述了喷气燃料燃烧产生的颗粒排放对人体健康和空气质量的影响。研究表明，100%的saf比化石Jet A-1更清洁，对健康的风险也更小。然而，没有ASTM认证可用于商用航空的100%插入式SAF。未来的研究应该调查超过50%的SAF与Jet A-1混合燃烧和产生的排放，并探索SAF的新来源，如微藻、柳枝稷和甘蔗甘蔗渣。这项研究将支持更高SAF混合物的认证，加速向更可持续的航空旅行的过渡。研究新型原料对于扩大saf的可用性和可持续性至关重要，有助于使供应链多样化，减少对化石燃料的依赖。

Overview of combustion and emission characteristics of sustainable aviation fuels and standard JET A-1 fuel

Traditional JET fuels produced from petroleum sources contribute to greenhouse gas emissions and air pollution, negatively impacting human health and the climate. Several studies have shown that sustainable aviation fuels (SAF) from feedstocks such as seed and non-seeds oil (palm, canola, sunflower, Karanja, camelina and Jatropha), waste cooking oil, recycled pork fat, and municipal waste have the potential to replace fossil JET fuels. These renewable fuels are made from natural sources, helping to reduce greenhouse gas emissions. This study reviewed research conducted between 2017- February 2025. As a comparative analysis, it examined renewable and fossil JET fuel physicochemical characteristics: density, viscosity, calorific value, surface tension, freezing, and flash point. This comparative study assesses the combustion characteristics of SAF and JET A-1 fuels, focusing on parameters such as smoke point, ignition delay, ignition temperature, flame temperature, and heat release rate. This review describes the gaseous (CO₂, CO, SOx and NOx) and particulate emissions from burning sustainable and fossil jet fuel. This study has advanced the understanding of renewable fuel properties and quality, supporting the development of sustainable fuel alternatives. Compliance with ASTM D1655-23 and ASTM D7566-23b standards is critical for the acceptance of SAF as a viable energy source in aviation transport. This study also describes the effect of particle emissions from JET fuels combustion on human health and air quality. Studies show that 100% SAFs are cleaner and pose fewer health risks than fossil Jet A-1. However, no ASTM certification is available for 100% drop-in SAF for commercial aviation. Future research should investigate how SAF blends with more than 50% SAF mixed with Jet A-1 burn and the emissions produced, and explore newer sources for SAF, such as microalgae, switchgrass, and sugarcane bagasse. This research will support the certification of higher SAF blends, accelerating the transition to more sustainable air travel. Investigating novel feedstocks is essential for expanding the availability and sustainability of SAFs, helping to diversify supply chains and reduce reliance on fossil fuels.
