The article discusses how additives can be used to improve biofuels for aviation use. Different additives can help biofuels meet the strict requirements of aviation fuel. For example, additives can reduce the negative effects of water content in oxygenated fuels. They can also enhance the performance of hydroprocessed alternative fuels by providing antioxidants and lubricity improvers. Additives can address issues like seal swelling, soot formation, and water content in biofuels. By using additives, it is possible to create cost-effective solutions that allow for the use of higher biofuel blends in aviation.
