Specialty hydroprocessing (Nebula®)
Nebula® bulk metal hydroprocessing catalyst delivers up to two times the activity of traditional hydroprocessing catalysts. Jointly developed by ExxonMobil and Albemarle Corporation, pioneering Nebula catalyst technology provides exceptional hydrogenation power, increasing hydrodesulfurization (HDS), hydrodenitrogenation (HDN) and aromatic saturation activity.
Up to two times more active than conventional catalysts
Stacked-bed maximizes total system performance
High yield and product quality
Upgrades difficult feeds to high-value products
Increases production of on-spec distillate products
Increases throughput
Improved margins after short payback period
Low investment to meet regulatory requirements
Can be a drop-in solution for existing units
Hydroprocessing value
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. For ultra-low sulfur diesel, Nebula catalyst technology lets refiners enjoy small capital investment to meet regulatory requirements. For LCO hydrocracker, the catalyst results in increased throughput and LCO to diesel VGO hydrocracking and improved yield and product quality.
Ultra-high activity
Nebula bulk metal catalysts have proven to be up to two times more active than conventional supported catalysts. Due to its high activity, and pairing with Albemarle’s STAX® technology, Nebula catalyst can be a drop-in solution for existing units. Nebula has more active sites per unit catalyst volume, and usually accounts for 15-35 percent of the reactor load.
Proven performance
Outstanding market acceptance: 60 individual users with over 5,000 MT sold
Exceptional customer loyalty: 85 to 90 percent repeat customers and more than one new customer every two months
