Biphasic catalytic upgrading of vegetable and cooking oils and animal fats to jet fuels

Unmet Need: Single-step efficient, cost-effective process for bio-jet fuel generation

Biomass is one of the biggest contributors of renewable energy. Current methods for production of bio-jet fuel from biomass include multiple pathways which include complicated processes for renewable jet process, catalytic process and pyrolysis. Notwithstanding the high yield of jet fuel, the complicated process increases the operating cost in the aviation industry. Existing single step processes are inhibited by low yield and poor deoxygenation rate, require high reaction temperature and hydrogen pressure increasing the energy and equipment cost.

The Technology: Biphasic tandem catalytic process to convert triglycerides to bio-jet fuels

A biphasic process is presented as a one-pot production of renewable jet fuel, which simplifies the existing traditional industry process. It exhibits lower reaction temperature and pressure resulting in decreased operation cost. A deoxygenation product is used as solvent which gives good performance in the reaction. The catalyst with suitable wettability exhibits higher catalytic activity in producing renewable jet fuel under mild reaction conditions and renewable diesel at lower reaction temperature.



•       Transportation fuel mainly in aviation industry as jet fuels.

•       Fuels generated from biomass are used for hydrogen storage. 


•       Simple single step process implementation.

•       The process has a lower reaction temperature and uses catalysts with higher catalytic activity.

•       The process is cost-effective.
