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.
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
