Through unprecedented hydrodesulferization (HDS), hydrodenitrogenation (HDN) and aromatic saturation activity, Celestia™ ultra-high activity, bulk-metal hydroprocessing catalyst can provide you with step-out performance and operational flexibility

Celestia catalyst application
Celestia catalyst is jointly developed by industry leaders ExxonMobil and Albemarle. Often deployed with its predecessor, Nebula®, the new Celestia catalyst provides operational flexibility, exceptional earnings and refinery optimization to add value beyond the hydrotreating battery limits. Commercial applications of these technologies are available in distillate hydrotreaters, as well as in light cycle oil (LCO) and vacuum gas oil (VGO) hydrocracker pretreaters.

Proven performance
Based on the expertise gained through more than a decade of commercial experience with Nebula, Celestia was developed by ExxonMobil and Albemarle as the next step in advancing catalyst technology. Since 2015, Celestia has demonstrated step-out performance and created new opportunities for growth at ExxonMobil facilities. Now it is available to refiners in fuels application.

Hydroprocessing value
The Celestia™ catalyst activity, when used well, can help improve margins by delivering value beyond the hydrotreating unit battery limits in many ways, including:
Processing challenged/opportunity crudes
Enabling feed scale-up
high-value products in the refinery
