Specialty hydroprocessing – Nebula® catalyst – factsheet

Nebula® bulk-metal hydroprocessing catalyst delivers up to two times the activity of traditional catalysts, helping refiners upgrade difficult feeds to diesel and other high-value products. Jointly developed by ExxonMobil and Albemarle Corporation, pioneering Nebula catalyst technology provides exceptional hydrogenation power, increasing hydrodesulfurization (HDS), hydrodenitrogenation (HDN) and aromatic saturation activity. Refiners use Nebula catalyst technology to upgrade difficult feeds to diesel and other high-value products, as well as to increase production volumes of on-spec distillate products.
