Second generation renewable fuels such as HEFA, HEFA-SPK (Sustainable Aviation Fuel or SAF), renewable diesel and bionaphtha are produced by hydroprocessing Used Cooking Oils (UCOs) or/and different vegetable oils like Canola Oil, Corn Oil, Camelina Oil, Rapeseed Oil, Sunflower Oil, Soybean Oil, Palm Oil, Tallow & Jatropha. The bio-based feeds have a higher content especially of phosphorous and oxygen but lower metal contents such as Na, Ca, K & Mg compared with fossil-based feedstock.
The operating pressure depends on Nitrogen content of the feed. The Hydrogen (H2) consumption depends on the type of feed since palm oil has 0.5-0.6 double bond per chain while sunflower oil has 1.6 double bond per chain:- Palm oil: 40-45 Nm3/m3
- Sunflower oil: 100-110 Nm3/m3 only for double bonds saturation
Hydrogen requirements for hydroprocessing triglycerides are typically:
- Cracking: 65 Nm3/m3
- Decarbonylation: 65-70 Nm3/m3 f
- Hydrodeoxygenation: 200-210 Nm3/m3
- Decarbonylation + Methanation: around 270 Nm3/m3
If methanation occurs then the advantage of decarbonylation + decarboxylation over hydrodeoxygenation in terms oh H2 consumption shall disappear.
