ExxonMobil introduces renewable diesel process technology

ExxonMobil Catalysts and Licensing LLC has introduced ExxonMobil Renewable Diesel process technology (EMRD) to meet changing mobility needs while using renewable raw materials. This new process technology converts raw materials, including but not limited to vegetable oils, unconverted edible oils and animal fats, into renewable diesel.

“Choosing the right process technology is crucial in order to produce both renewable diesel and jet fuel from organic raw materials. The EMRD process offers an advanced solution that enables high yields while meeting strict seasonal product specifications. “

    • Meets advanced cold flow specifications while enabling high yields through the use of BIDW ™ catalyst technology for dewaxing

    • Provides superior performance through a two-step process versus a one-step process

The EMRD process is a two-step process in which hydrotreating and dewaxing are controlled separately. Compared to a one-step process, this approach offers higher diesel yields and better control. In addition, the EMRD process offers the potential to produce aviation fuel as a by-product with additional fractionation.

The EMRD process is an integrated solution that uses ExxonMobil’s Bio-Isomerization Dewaxing (BIDW) catalyst. This provides refiners and biofuel manufacturers with powerful dewaxing in both winter and summer modes. When the BIDW catalyst was tested against other internally formulated zeolite-based alternatives, improved yields were demonstrated.

“Choosing the right process technology is crucial in order to produce both renewable diesel and jet fuel from organic raw materials. The EMRD process provides an advanced solution that enables high yields while meeting strict seasonal product specifications, ”said James Ritchie, President of ExxonMobil Catalysts and Licensing LLC.

With a keen interest in producing renewable aviation fuel as a primary product, ExxonMobil is also developing advanced catalyst and process technology solutions that give EMRD process licensees the flexibility to adjust the amount of aviation fuel produced compared to diesel.
