Introducing Celestia™ - An ultra-high-activity hydroprocessing catalyst for increased flexibility and profitability  

Celestia™ hydroprocessing catalyst is designed for refinery leaders focused on margin improvement. Celestia offers the highest hydrodesulfurization (HDS), hydrodenitrogenation (HDN) and aromatic saturation activity of any hydroprocessing catalyst in the industry. Jointly developed by ExxonMobil and Albemarle, Celestia is deployed alongside Nebula®, its predecessor, to provide operational flexibility, superior earnings and refinery optimization, also adding value beyond the hydrotreating battery limits.

Increased flexibility and profitability from new hydroprocessing catalyst

Celestia™ bulk-metal catalyst enables upgrading more difficult feeds and delivering products to meet environmental standards and higher quality levels.   


Ways for refiners to capitalize on the benefits of ultra-high-activity catalysts

There are multiple ways to deliver improved margins. Typical examples include increasing feed rate, increasing feed difficulty, increasing yield and improving product quality.
