Ebullated-Bed Hydrocracking Gains Share Over Delayed Coking
Refiners upgrading residue increasingly favour ebullated-bed hydrocracking over delayed coking, since hydrocracking converts residue directly into distillate rather than low-value petroleum coke, and rising coke inventories in several markets have compressed coking economics meaningfully. Saudi Aramco's Jazan refinery and several Chinese independent refiners have commissioned ebullated-bed units since 2023, each requiring continuous catalyst addition and withdrawal rather than the batch change-out cycle standard FCC units use. Chevron Lummus Global and Axens both report expanding order books for ebullated-bed catalyst systems tied to committed megaproject capacity coming online through the back half of the decade.
