Hydrocracking SAF Catalyst segmentation is driven primarily by three application categories. Jet fuel production accounts for roughly 45 % of catalyst demand, as refiners target high‑volume sustainable aviation fuel (SAF) blends to meet airline carbon‑neutrality goals. The Diesel blending segment contributes about 35 %; hydrocracking catalysts enable the conversion of heavy fractions into diesel‑range SAF, supporting regional distribution networks. The remaining 20 % is attributed to Blendstock upgrading, where catalysts improve the quality of intermediate streams before final blending. Within each application, catalyst types are differentiated into Zeolite‑based (e.g., ZSM‑5, Zeolite Y), Metal‑oxide (e.g., Ni‑Mo, Co‑Mo), and Bifunctional systems (e.g., Ni‑W/Zeolite). Zeolite‑based catalysts dominate jet‑fuel applications due to their shape‑selectivity, while metal‑oxide variants are preferred for diesel upgrading because of their hydrogenation activity. Bifunctional catalysts bridge both needs, offering balanced activity that sustains overall market growth by addressing diverse refinery configurations.
