生物航煤生产技术的发展现状

Development of bio-jet fuel production technology:a review

由于温室气体的大量排放和对化石燃料的高度依赖,航空业的可持续发展得到了全世界的关注。生物航煤被认为是一种有前景的传统航空燃料替代品。本文概述了制备生物航煤的代表性工艺技术路线、发展现状以及生物航煤产业发展所面临的机遇和挑战。迄今为止,已经有多种生物航煤制备工艺得到美国材料实验协会(American Society for Testing and Materials,ASTM)认证。其中,酯和脂肪酸加氢是目前最为成熟、可以实现完全商业化的路径。考虑到技术经济性和成熟度,短期内,费托合成是比较有发展前景的工艺。

Due to the large amount of greenhouse gas emissions and the high dependence on fossil fuels,the sustainable development of aviation industry has attracted worldwide attention.Bio-jet fuel is considered to be a promising alternative to traditional aviation fuel.This article summarizes the representative technological route,development status,opportunities and challenges faced by the development of bio-jet fuel industry.So far,several bio-jet fuel production technologies have been certified by the American Society for Testing and Materials(ASTM).Hydroprocessed esters and fatty acids is currently the most mature process that can be fully commercialized.Considering economic characteristics and technology maturity,Fischer-Tropsch is promising in near term.
