Diesel Dewaxing

Increase your profits with MIDW™ dewaxing catalyst – one of the world’s most versatile fuels technologies.  

ExxonMobil’s MIDW™ catalyst technology and services provide high yields of low cloud point diesel. The process uses a proprietary catalyst that converts waxy paraffins to higher performance molecules, compared to older technologies that rely on cracking. By using MIDW technology, refiners gain a much higher diesel yield, particularly for deep reductions in cloud point. Read our case studies and white papers to learn more about our diesel dewaxing technology.

Refiner generates ~$20 million in annual benefits with MIDW™ catalyst

A refiner producing ultra-low-sulfur diesel eliminated endpoint giveaway by implementing MIDW™ drop-in catalyst technology in an existing hydrotreater, generating estimated annual benefits of $20 million. 

Refiner increases distillate yield by 42% with MIDW™ catalyst

A North American refiner increased distillate yield by 42%, achieving an estimated annual benefit of $10 million, by switching from a cracking dewaxing catalyst to MIDW™ drop-in catalyst solution.

Increase diesel yields – and profits – for your refinery

ExxonMobil Catalysts and Licensing offers an effective way to modify the cold-flow properties in diesel: MIDW™ technology for isomerization dewaxing of distillate fuels. It’s a relatively simple drop-in catalyst solution for dewaxing diesel that efficiently uses existing plant equipment.

Refiner dramatically improves diesel yield by converting to MIDW™ technology

By switching to MIDW™ technology from a cracking-based dewaxing catalyst, a U.S. refiner gained a big margin impact.

Maximize your product slate with diesel in cold climates

This white paper examines the three primary specifications for producing diesel in cold climates – cloud point, low filter plugging point and pour point – and the options for achieving target specifications. Traditional options, as well as ExxonMobil's isomerization dewaxing technology, are explored for increasing production of ultra-low-sulfur diesel.

Boost diesel yields with MIDW™ catalyst technology

ExxonMobil’s MIDW™ diesel dewaxing catalyst technology converts waxy paraffins to higher performance molecules, as compared to older technologies that rely on cracking, resulting in a much higher diesel yield.
