Praj and Axens Demonstrate Ethanol-to-Jet Pathway for Sustainable Aviation Fuel

Key highlights
  • Praj's demo plant at Praj Matrix validated bio-ethanol as a feedstock for SAF.
  • Axens provided Jetanol™ technology, including dehydration, oligomerization, and hydrogenation.
  • The SAF is compliant with ASTM D7566 and compatible with existing aviation infrastructure.
  • Praj supported India's first commercial SAF-blended flight with Indian Oil.

Demonstration of Ethanol-to-Jet Process

Praj Industries has successfully demonstrated its Ethanol-to-Jet (EtJ) process using Axens Jetanol™ technology at its Integrated Sustainable Aviation Fuel (SAF) demonstration plant at Praj Matrix. This marks a significant milestone in the transition to low-carbon aviation fuels.

Technological Readiness and Validation

The SAF demo plant, previously inaugurated by India's Union Minister for Petroleum and Natural Gas, has proven its technological readiness for both Alcohol-to-Jet (AtJ) pathways. After demonstrating bio isobutanol as a feedstock, the plant has now validated bio-ethanol under the EtJ pathway, enhancing the versatility of Praj's SAF technology portfolio.

Collaboration with Axens

Axens, a global provider of process technologies, has partnered with Praj to advance SAF through the AtJ route. Axens has licensed its Jetanol™ technology to Praj, which includes dehydration, oligomerization, and hydrogenation steps, along with catalysts and technical support.

Commercial Deployment and Compatibility

This achievement positions Praj as the first company to offer a fully integrated, end-to-end technology solution for the AtJ pathway, covering both isobutanol and ethanol. The SAF produced is compliant with ASTM D7566 and fully compatible with existing aircraft engines and infrastructure.

Real-World Application

Praj has previously demonstrated real-world SAF deployment in India, supporting the country's first commercial passenger flight powered by SAF-blended aviation turbine fuel. An AirAsia India flight operated from Pune to New Delhi using SAF supplied by Praj in collaboration with Indian Oil.
