The Shell XTL process for bio-SAF and synthetic SAF

Sustainable aviation fuel (SAF) is widely recognised as a critical lever for decarbonising aviation.

Currently, refineries focus on producing bio-SAF from easier-to-process feedstocks such as used cooking oils and animal fats. A key challenge on the horizon, however, is binding targets from ReFuelEU Aviation to produce more SAF from more challenging feedstocks, such as biomass residues, and using renewable power and carbon dioxide (CO₂).

In particular, synthetic SAF (also called eSAF or RFNBO-SAF), made using power-to-liquids (PTL) technology, has high potential because the feedstocks (solar and wind energy, CO₂ and water) are in virtually endless supply. Combining production of synthetic SAF and bio-SAF can be an enabler for early projects.

In this webinar we:

summarise the decarbonisation levers for aviation;
outline various bio-SAF and synthetic SAF technology pathways; and
introduce the Shell XTL Process, which offers an integrated solution for bio-SAF and/or synthetic SAF production.

The Shell XTL Process leverages lessons learned from Shell’s integrated GTL technology, as applied at Pearl GTL in Qatar, the world’s largest integrated GTL facility.

RFNBO: renewable fuel of non-biological origin; XTL: anything (renewable/sustainable/low-carbon)-to-liquids; GTL: gas-to-liquids

Shell Catalysts & Technologies is committed to sharing knowledge, expertise and best practices.
