ExxonMobil technology to enhance SAF production

ExxonMobil has announced a unique process technology to enable the manufacture of sustainable aviation fuel (SAF) from renewable methanol.

“SAF produced from renewable methanol can play an important role in helping the aviation industry achieve the transition to a net zero future. Reaching that goal by 2050 will require a multi-faceted approach, including advancements in aircraft-related technology, changes to infrastructure and operations, and a dramatic increase in SAF supply. Our process technology can be an important step in this direction,” said Russ Green, ExxonMobil’s lower-emission fuels venture executive.

ExxonMobil has a long history of developing advantaged proprietary process technologies and catalysts to make energy products that society needs. The company is leveraging its core capabilities to develop a solution that converts methanol to SAF.

Methanol derived from the gasification of biomass and waste, as well as from lower-carbon hydrogen and captured carbon dioxide (CO2), can be converted into SAF using ExxonMobil’s methanol-to-jet proprietary process technology and catalysts. Preliminary estimates by ExxonMobil suggest that this solution has a higher yield of jet fuel than other options. The ExxonMobil solution also provides the flexibility to use a mix of alcohols as feedstock, and produce renewable diesel and lower-carbon chemical feedstocks.

“Methanol to jet technology is scalable and suitable for the conversion of methanol produced from today's world-scale plants. The work necessary to qualify the resulting renewable jet fuel pathway has already started,” said James Ritchie, President of ExxonMobil Catalysts and Licensing LLC.

Additionally, ExxonMobil has process technology and catalysts that are available to customers today which convert other renewable biofeeds, such as used cooking oils, animal fats, and vegetable oil, into renewable jet fuel. Analysis shows that the company's BIDWTM isomerisation catalyst provides a jet fuel yield advantage vs the alternatives that are currently available.

ExxonMobil is evaluating opportunities to deploy these process technology solutions within a portfolio of options to help the aviation industry to decarbonise.

“ExxonMobil is advancing integrated solutions to extend our carbon capture & storage (CCS) and hydrogen capabilities to support the decarbonisation objectives of our biofuels customers and partners,” said Siva Ariyapadi, Bioenergy Global Business Manager.
