High carbonaceous emissions motivate the development of sustainable jet fuel (SAF), which lowers CO2 pollution due to its high cycloalkane content. Cycloalkanes can upgrade heating values and thermal stability of jet fuels because of their high energy density and are primarily produced from woody lignin, which can face a new issue regarding scarcity of woody biomass. Exploration of nonwoody-based biomass lignin for cycloalkane production can overcome this problem. The main purpose of this chapter is to investigate promising raw materials as new nonwoody lignin-based cycloalkane resource. The effects of cycloalkane addition towards SAF, such as density, kinematic viscosity, specific energy, cetane number, freezing point, flash point, etc., are also presented. At present, valorization of nonwoody lignin is still centered on corn, which is a gap and highly competitive with food industries. The development of other potential feedstocks, including solid waste biomass, as new nonwoody lignin-derived cycloalkane sources is a good approach associated to their high lignin content. The addition of nonwoody lignin-based cycloalkanes in SAF shows good physicochemical characteristics, which comply with ASTM D7566 and D1655. The use of ILs-doped solid base catalysts in the nonwoody-based cycloalkanes-rich SAF production can allow a novel invention and increase the catalytic performance. This is attributed to stronger Brønsted-Lewis acidity, van der Waals forces, and higher thermal and chemical stability. Furthermore, it can reduce the process cost caused by the cost-effectiveness of base catalysts and the regenerability and reusability of ILs.
