The MSDW™ lubricant dewaxing catalyst from ExxonMobil is designed to enhance the production of high-quality base stocks with improved cold-flow properties. This catalyst utilizes proprietary shape-selective technology, incorporating zeolites and noble metals, to selectively isomerize n-paraffins and saturate aromatics while minimizing fuel cracking. It demonstrates exceptional activity and tolerance to contaminants such as nitrogen, sulfur, and aromatics, allowing for stable operation even with degraded feed quality.
MSDW™ is compatible with a wide range of feedstocks, including hydrotreated and hydrocracked oils, and is capable of producing base stocks classified in API Groups II to III+, with viscosity grades ranging from 2 to 25 cSt at 100°C. The catalyst has a proven track record of high yields and long operational life, with some units operating for over 12 years without needing a catalyst change. Ongoing research and development efforts aim to further enhance yield and feedstock tolerance, solidifying MSDW™ as a leading choice for refiners seeking to maximize profitability and product quality.
ExxonMobil’s MSDW™, MAXSAT™ and MWI™ catalyst technologies produce high-quality, high-performing lubes base stocks. These technologies incorporate proprietary ExxonMobil catalysts and deliver outstanding activity, yield, selectivity, run length and durability. Our MSDW catalyst has demonstrated this for nearly 20 years. Our MAXSAT and MWI catalysts also deliver benefit-rich performance.
Key Benefits:
Higher Performance
Low Risk
Exceptional Quality
In today’s world, standing still corresponds to stepping backward. At ExxonMobil, we have active R&D to continue to boost yield, further improve tolerance to heteroatom contaminants and broaden the range of acceptable feedstocks.
