Abstract: With the depletion of oil resources, the increasing pressure of CO₂ emission reduction and the increasing demand of aviation industry, the development of bio-jet fuel technology is an inevitable requirement to realize the green and sustainable development of aviation industry in China. In the production of bio-jet fuel, the technology of hydroconversion of vegetable oils to jet fuel is relatively mature, short and low-cost processes, which has been widely concerned. In this paper, the specifications of jet fuels and the compositions and characteristics of vegetable oils are introduced. The main reactions of this process are discussed in detail. The latest progresses of vegetable oil hydroconversion to jet fuel are summarized. The possible research directions of this process to produce bio-jet fuel are prospected.

Key words: bio-jet fuel, vegetable oil, hydroconversion
