Hydrotreating of Triglyceride Feedstock to Produce Renewable Aviation Fuel

Renewable aviation fuel has been identified as the most promissory alternative for the sustainable development of the aviation sector. This renewable fuel can be obtained from triglyceride, lignocellulosic biomass, sugar and starchy feedstock through different processing pathways; however, the hydroprocessing of triglyceride feedstock is the most advanced technology. The modeling and simulation of the hydrotreating processes is a key step to improve it from an energetic point of view; this can be realized through the application of strategies such as energy integration or process intensification. Nevertheless, the reliability of the obtained results depends strongly on reactive and phase equilibrium calculations. In particular, in the hydrotreating process, the conversion of triglyceride feedstock intro hydrocarbons is the key step; and it has been of recent interest in research areas. Therefore, in this work, a review of the kinetic models and global conversions reported for biojet fuel production through hydrotreating process of renewable triglyceride feedstock is presented.
