ExxonMobil Catalysts and Licensing LLC (ExxonMobil), a subsidiary of ExxonMobil Chemical Company one of the world's largest chemical companies has introduced ExxonMobil Renewable Diesel (EMRD) process technology to help meet the evolving needs for mobility while utilizing renewable feedstock. This new process technology converts feedstocks including, but not limited to, vegetable oils, unconverted cooking oil, and animal fats, into renewable diesel.

The EMRD process is a two-stage process in which hydrotreating and dewaxing are controlled separately. Compared to a single-stage process, this approach, the company says, provides higher diesel yields and superior control. Additionally, the process provides the potential to produce jet fuel as a secondary product with added fractionation.
The EMRD process is an integrated solution that leverages ExxonMobil’s Bio-Isomerization Dewaxing (BIDW) catalyst. This provides refiners and biofuel producers with powerful dewaxing in both winter and summer modes. Improved yields were demonstrated during the testing of BIDW catalyst versus other internally formulated zeolite-based alternatives.
Choosing the right process technology is critical to producing both renewable diesel and jet fuel from bio-feedstocks. The EMRD process provides an advanced solution that enables high yields while meeting stringent seasonal product specifications, said James Ritchie, President of ExxonMobil Catalysts and Licensing.
Due to significant interest in producing renewable jet fuel as a primary product, ExxonMobil is also developing advanced catalyst and process technology solutions that will offer EMRD process licensees flexibility to tailor the amount of SAF versus renewable diesel produced.
