2. Production, composition and physico-chemical properties of alternative jet fuels

2.1 Production processes for alternative fuels and jet fuels

The processes used to produce alternative synthetic jet fuels are generally the same as those developed to produce alternative diesel fuels, as the physico-chemical characteristics of these two types of fuel are quite similar. Most of the processes developed to produce alternative diesel fuels are therefore capable, with a few adaptations, of producing alternative jet fuels, and vice versa.

Alternative fuel production processes are extremely numerous, and at very different stages of development, ranging from laboratory concepts (a few grams or tens of grams/day: low TRL of 1 to 3 (figure 5...
