Abstract

The aviation sector is a major emitter of fossil fuel-derived carbon dioxide contributing to global warming. For instance, jet fuel consumed by the aviation industry is 1.5–1.7 billion barrels per year, resulting in 705 million metric tons of carbon dioxide emissions. Aircraft manufacturers have set ambitious goals, aiming for carbon-free growth post-2020 and a 50% reduction in greenhouse gas emissions by 2030. This issue can be solved by replacing fossil fuels with biofuels produced from modern biomass, thus meeting the carbon neutral objective. Here, we review the technologies to convert biomass into jet biofuel with focus on reactants, catalysts, and the chemistry of combustion. Reactants include alcohols, oil, esters, fatty acids, gas and sugars. Catalysts include Fischer–Tropsch catalysts, palladium, platinum, ruthenium, nickel, and molybdenum. The utilization of jet biofuels could potentially reduce greenhouse gas emissions by up to 80%. We also discuss economic implications.

生物质催化生产航空喷气生物燃料的研究进展

航空业是化石燃料产生的二氧化碳的主要排放源，导致全球变暖。例如，航空业每年消耗的航空燃料为15 - 17亿桶，导致7.05亿吨二氧化碳排放。飞机制造商制定了雄心勃勃的目标，旨在2020年后实现无碳增长，到2030年将温室气体排放量减少50%。这个问题可以通过用现代生物质生产的生物燃料取代化石燃料来解决，从而达到碳中和的目标。本文综述了将生物质转化为喷气生物燃料的技术，重点介绍了反应物、催化剂和燃烧化学。反应物包括醇、油、酯、脂肪酸、气体和糖。催化剂包括费托催化剂、钯、铂、钌、镍和钼。喷气生物燃料的使用可能会减少高达80%的温室气体排放。我们还讨论了经济影响。

期刊介绍： Environmental Chemistry Letters explores the intersections of geology, chemistry, physics, and biology. Published articles are of paramount importance to the examination of both natural and engineered environments. The journal features original and review articles of exceptional significance, encompassing topics such as the characterization of natural and impacted environments, the behavior, prevention, treatment, and control of mineral, organic, and radioactive pollutants. It also delves into interfacial studies involving diverse media like soil, sediment, water, air, organisms, and food. Additionally, the journal covers green chemistry, environmentally friendly synthetic pathways, alternative fuels, ecotoxicology, risk assessment, environmental processes and modeling, environmental technologies, remediation and control, and environmental analytical chemistry using biomolecular tools and tracers.
