Abstract
Aviation industry is one of the main contributors and fastest-growing sectors in the world economy. Fuel consumption from this industry is one of the major issues that have drawn the attention of both professionals and researchers in recent years. The high dependency along with the high consumption of aviation fuel on petroleum plays a crucial role in environmental degradation due to increased carbon dioxide and other emissions, as well as in the increasing rate of fossil fuel depletion. Therefore, various potential technologies have been developed and further investigated to produce alternative aviation fuels, especially biofuels. In this article, principles, sustainability, and main concerns of different alternative aviation fuel processing technologies, with some focus on biofuels, are discussed in challenges and possible remedies. The major ecological problems connected with the application of conventional jet fuels in contrast to The advantages of biofuels implementation in the aviation industry are also highlighted. This work is aimed to show the state of the art of current alternative aviation fuels, their production technologies, and the potentiality of replacing the conventional jet fuel.
Highlights
The environmental condition is on our headlines due to the pollution and depletion of petroleum
The environmental challenges due to greenhouse emissions focused during fuel selection and the process of production
Various alternative aviation fuel processing technologies have been reviewed based on different renewable sources and feedstocks
Summary
The environmental condition is on our headlines due to the pollution and depletion of petroleum. The aviation industry is developing due to the rise up the number of passengers flying across the world, so the demand for production and supply process should not get affected. The hike in the price of the fuel directly hit on availability and thoroughly shifted to alternative sources or production technology. Among environmental impact factors of aviation, emissions to air, especially at high altitudes, emissions from ground operations (airport operations, fuel production, etc.) and noise, as well as the sustainability of the overall sector, are of significant importance. This paper outlines the possibilities for alternative jet fuels in the near and mid-term future, giving a background for jet fuel processing technology. Introspection of Alternative Aviation Fuel Processing Technology: Benchmarks and Challenges. Possible future fuels are introduced shortly and their potential for future use as aviation biofuels is discussed
