Engineer going through catalytic dewaxing

Fuel production  

ExxonMobil has been a leading provider of fuel refining technologies that meet customer needs for high-quality transportation fuels.

  • MIDW™ technology and services

    The global demand for diesel, tighter specifications in cold climates and the increasing use of waxy crudes led ExxonMobil to develop technologies to maximize the production of high-quality diesel with good low-temperature properties. MIDW technology and services utilize an ExxonMobil proprietary catalyst that lowers the cloud point of diesel through isomerization of paraffins far better than technologies that rely on cracking, resulting in a much higher diesel yield – particularly for deep reductions in cloud point.

    MIDW technology is versatile, and in addition to cloud point reduction can also be used for:

    • Endpoint extension in a hydrocracker operation using a small unit to process the heavy cut, placing a bed of MIDW catalyst in an existing ULSD unit or spare reactor in series – a two-stage operation
    • Low-pressure applications and at high space velocities with very good dewaxing performance
    • Trim dewaxing by adding our specialty catalyst to an existing hydrotreater, allowing flexibility by quenching the catalyst during the summer operation to avoid reducing the cloud point

    The success of MIDW technology is based on continuous innovation with new materials, processes and rigorous testing. More than 11 MIDW units are operating around the world with concentration in cold climates (Russia, North America, Northern Europe), but also in the Middle East, India and Singapore that produce Euro V diesel for export. The ability to retrofit an existing unit with MIDW technology to capture significant value makes this one of the most sought-after fuels technologies in the world today.

  • BenzOUT™ technology and services

    BenzOUT technology and services have been commercially proven for benzene reduction in gasoline. BenzOUT technology converts benzene, typically in a light reformate stream to higher alkylaromatic blending components by reacting a benzene-rich stream with light olefins, such as refinery-grade propylene stream. This technology avoids the octane loss and hydrogen consumption associated with benzene saturation alternatives. It provides a unique process advantage to help refiners meet benzene regulations while at the same time achieving an attractive economic return on their investment.

    BenzOUT technology was developed by ExxonMobil and is available for license through Badger Licensing LLC.


    • Fixed bed liquid-phase reactor results in low utility requirements
    • Grass roots or it can be retrofitted into an existing facility, such as a polygas unit
    • Highly selective and stable catalyst enabling the process to run at a very high benzene conversion
    • Upgrading of light olefins and benzene into high octane alkylaromatic blendstock would also result in a volume swell of the gasoline pool
    • 2-5 numbers of (R+M)/2 gain in a full reformate, depending on the feed composition
    • Maintain hydrogen balance by sending all the C6 components (low blending octane values) to the reformer unit
    • Low temperature liquid phase process
    • No hydrogen consumption

  • SCANfining™ technology and services

    ExxonMobil’s SCANfining technology for hydroprocessing offers a cost-effective solution for meeting the low-sulfur requirements of reformulated gasoline. The technology employs a unique proprietary catalyst system to selectively remove sulfur. With this proven, low-cost approach to reducing gasoline pool sulfur available from a single source, a customized system can be designed to meet the individual needs of each refiner.

    SCANfining technology can be retrofitted using existing equipment. The technology has been developed with different configurations to provide refiners the flexibility to choose the lowest investment cost approach. ExxonMobil’s continued focus on gasoline hydrofining technology through process improvements and catalyst developments is geared toward a cost-efficient investment approach to meeting the stringent gasoline sulfur specifications while minimizing octane loss.

    SCANfining technology has been proven worldwide in successful commercial use since the 1990s. There are 43 units operating within ExxonMobil and licensees’ refineries worldwide with over 1.3 million barrels per day of capacity.


    • Commercially proven performance
    • Demonstrated reliability
    • Operating flexibility
    • Options for low capital investment
    • Customized solutions engineered to variety of configurations

  • Sulfuric acid alkylation

    Achieving more value from every cut of the crude barrel is a major refining objective. Upgrading light olefins and isobutane to alkylate with ExxonMobil’s sulfuric acid alkylation process offers refiners that opportunity. Our proven technology combines propylene, butylene and pentylene with isobutane to form high-value alkylate that is ready for gasoline blending.


    • Lower power costs for refrigeration and mixing compared to competitive systems
    • No heat exchanger inside reactor means a lower investment
    • Ideal blendstock meets tough mogas specs: < 3ppm sulfur, low RVP, no aromatics and no olefins
    • High octane product ready for gasoline blending
    • Reliable low heat, low pressure system vaporizing C4s rather than using a heat exchanger bundle in the reactor
    • Demonstrated run lengths greater than four years between turnarounds
    • Proven commercial experience with 16 units spanning nearly 60 years of commercial experience
