Lubricant base stock hydrofinishing (MAXSAT™ catalyst)
ExxonMobil’s MAXSAT™ is a proprietary, state-of-the-art aromatic saturation catalyst that integrates well with lubes or fuels hydrocrackers or as a hydrofinishing step with hydrodewaxing technologies. Refiners use MAXSAT as a hydrofinishing catalyst to enhance the color, oxidative and thermal stability of the base stock.
Process full range of viscosity grades to maximize value
Produces base stocks with outstanding color and stability
Exceptional base stock products
MAXSAT is a noble-metal hydrofinishing catalyst with a proprietary support that is more polar tolerant and cost-effective than existing hydrofinishing catalysts. Due to its high sulfur tolerance and exceptional saturation capability, MAXSAT produces base stocks with excellent color and stability.
MAXSAT process
MAXSAT™ services include:
Initial non-confidential consultations
Development of licensing proposal
Basic engineering package, including basic design specification and operating guide
Engineering support during FEED and EPC stages
Technology transfer, training, catalyst loading and startup support
Performance estimates for catalyst refills
MAXSAT hydrofinishing
MAXSAT removes polynuclear aromatics (PNAs) and trace amounts of olefins. PNA equilibrium is controlled by reaction temperature and pressure. MAXSAT is highly efficient at aromatic saturation even in the presence of moderate amounts of polars.
Proven performance
Commercially proven MAXSAT technology provides:
High saturation activity
High sulfur tolerance
Low density
MAXSAT’s low density helps limit catalyst cost by minimizing the total weight of hydrogenation metal needed. As a drop-in catalyst, MAXSAT has demonstrated excellent performance when integrated with other processing equipment.
