SAF is addressed from different angles. Plastics pyrolysis, tyre pyrolysis, and vegetable oils are a few examples. They all have different types of contaminants compared with fossil fuels. Some adsorbents are used to remove some contaminants. However, they are not able to reduce the concentration significantly. Hydrotreating is required. Isoterra for vegetable oil uses hydrotreating. Plastic pyoil requires hydrotreating to reduce chlorides and nitrogen. For chemicals production, adsorbents meet the specification in some cases.
