Systems And Methods For Renewable Fuel

Patent No. EP2852657 (titled "Systems And Methods For Renewable Fuel") was filed by Ensyn Renewables on Dec 11, 2012. The application was issued on Jan 23, 2019.

Patent Summary

A method for preparing fuel involves co-processing a feedstock in the presence of a catalyst within a fluidized catalytic cracker. The feedstock comprises 80–99.95 wt.% petroleum fraction and 0.05–7 wt.% unenriched renewable fuel oil. This renewable fuel oil is produced by mechanically grinding cellulosic biomass followed by rapid thermal processing, specifically excluding hydrodeoxygenation, hydrotreating, or catalytic processing. The unenriched renewable fuel oil is characterized by a moisture-free carbon content of 35–80 wt.%, a moisture-free oxygen content of 20–50 wt.%, and a water content of 10–40 wt.%. The resulting fuel is a product of this co-processing operation.
