Catalysts
-
Celestia™ catalyst
Delivering extraordinary results at ExxonMobil refineries around the world since 2015, Celestia bulk metal catalyst technology provides step-change benefits in hydrotreating activity and processing capability.
-
Nebula™ catalyst
Generating exceptional customer loyalty, Nebula catalyst technology provides ultra-high hydrogenation power, increasing hydrodesulfurization (HDS), hydrodenitrogenation (HDN) and aromatic saturation activity.
MIDW™ catalyst
Backed by forty years of ExxonMobil innovation in diesel dewaxing, MIDW catalyst technology provides high yields of low cloud point diesel, converting waxy paraffins to higher performance molecules.
