Sustainable Aviation Fuel Process Overview
1. Feedstock Selection: The first step in making sustainable aviation fuel is selecting the appropriate feedstock. New Rise has chosen to use the cleanest of the various feedstocks by primarily using corn oil.
2. Pre-treatment: The feedstock is pre-treated through a ‘degumming’ process which removes phosphatides as well as any other any impurities such as trace metals. This ensures that the feedstock used by the facility is of high quality, meets required specifications, and maximizes reactor catalyst life.
3. Hydrotreating: The pre-treated feedstock is then heated to high temperatures and mixed with hydrogen gas in the presence of a catalyst to undergo hydrotreating. The objective of hydrotreating is to deoxygenate renewable lipids in the presence of hydrogen to produce linear paraffins
4. Hydroisomerization: The next step in making sustainable aviation fuel involves hydroisomerization, which is the process of adding hydrogen to the product to improve its cold-flow properties. The objective of hydroisomerization is to upgrade the linear paraffins produced in the hydrotreating process into real drop-in middle distillate bio-based fuels.
5. Fractionation: After isomerization, the mixture is then fractionated to separate the different components of the fuel based on their boiling points. This allows for the separation of different compounds and ensures that the final products meet the required fuel specifications.
