ExxonMobil Catalysts and Licensing has introduced new renewable diesel process technology (EMRD) to help meet the evolving needs for mobility while utilising 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 provides higher diesel yields and superior control.
Additionally, the EMRD process provides the potential to produce jet fuel as a secondary product with added fractionation.
The process is an integrated solution that leverages ExxonMobil’s Bio-Isomerisation Dewaxing (BIDW) catalyst.
This provides refiners and biofuel producers with powerful dewaxing in both winter and summer modes. Improved yields were demonstrated during 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 LLC.
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 jet fuel versus diesel produced.
