The Digest’s 2024 Multi-Slide Guide to Better SAF via Adsorptive De-Nitrogenation

Hydrothermal liquefaction provides a straightforward approach to producing SAF, yet there’s nitrogen in the upgraded biocrude, and it has to come out.  Meanwhile, bad news, nitrogen in hydrotreated biocrude consists of a large variety of nitrogenated compounds: Amides and amines, but also non-basic and more refractory indoles, pyridines, pyrimidines, imidazole. Good news, Adsorptive De-Nitrogenation is an alternative to deep hydro-denitrogenation, is less severe and a more selective process.Daniel Miki Santosa, Peipei Wang, and Jian Liu of Pacific Northwest National Lab and Josh Thompson  Oak Ridge National Laboratory prepared this overview given at DOE Project Peer Review.
