**5.3 Jet fuel**

Alternative jet fuel typically contains a complex mixture of primarily n/iso-paraffins, cycloparaffins, and alkylbenzenes with a carbon number range of 9–15 [24]. Carbon tax accelerates the development of jet fuel from renewable resources. Lowering emissions of particles and greenhouse gases during the flight are the fundamental reason of trying alcohol fuels as a jet fuel option.

Using a 50/50 (v/v) blend of petroleum-based and lipid-based jet fuels for flight was already approved by the American Society for Testing and Materials (ASTM) committee. However, the lack of raw materials and relatively low jet fuel yield of this process limit its application [24].
