Status of Biofuels ISOCONVERSION Process Technology

CH ReactorPilot Scale

ARA has demonstrated the Biofuels ISOCONVERSION Process in bench-scale and pilot-scale reactor systems. Our 25 gallon-per-day bench-scale system has been in operation since 2008. The 3 barrel-per-day pilot-scale system, commissioned in 2010, includes heat recovery to demonstrate energy efficiency. The pilot system designs also allow for the recovery of valuable byproducts.

ARA and CLG have processed multiple 2,000 gallon samples of renewable oils into “drop-in” jet and diesel fuels.  Process operating conditions can be controlled to produce drop-in fuels with optimal aromatic and cycloparaffin contents.



ARA and CLG licensed the Biofuels ISOCONVERSION process technology on a non-exclusive basis for commercial scale production to Aemetis, Inc. in August 2012.

Historic Flight

October 29th 2012 will go down in history as the first time a civilian jet was powered by 100 percent renewable biofuelthat meets petroleum specifications without blending. Applied Research Associates (ARA) and Chevron Lummus Global (CLG) partnered with the National Research Council of Canada (NRC), the U.S. Air Force Research Laboratory (AFRL), and Agrisoma Biosciences Inc. to flight test ReadiJet® drop-in jet fuel in Ottawa. The ReadiJet® was produced by ARA, under contract to AFRL, from Agrisoma’s Resonance™ feedstock crop using CLG’s and ARA’s breakthrough Biofuel ISOCONVERSION process. Popular Science Magazine recently recognized the flight as one of 2012's 25 most important scientific events.

On December 31, 2012, Biofuels Digest named ARA/CLG’s fuels as the “Best New Fuel for 2012”.

Recent Developments

“We have continued to scale up our biofuels technology with a pilot reactor conversion system,” said Better Fuels Group technical lead Ed Coppola, who drives the technical and certification renewable fuel efforts that have taken off in recent years.

In January 2013, ARA joined forces with energy enterprise Blue Sun Energy to develop a demonstration-scale biofuels demonstration facility located in St. Joseph, Missouri to produce 100 barrels per day (or roughly 4,200 gallons a day). The demonstration system was commissioned and began 24/7 operations in March 2014. The fuel from the demonstration plant will be used to complete ASTM and MILSPEC certifications.

ARA researchers also operate a 20,000-square-foot facility in Panama City, Fla., for energy research and development projects. The Better Fuels Group works in this production and prototype facility to ensure our fuels meet requirements as distillation temperatures, viscosity and chemical composition specifications.

In addition to the 100 barrel per day system in St. Joseph, the team operates four different bench and pilot scale reactor systems that convert plant oils and other feed stocks into a synthetic crude oil at rates up to 160 gallons per day. Two batch and one continuous-flow hydrotreating systems enable researchers to convert the synthetic crude oil into a pure hydrocarbon product that is then distilled into jet and diesels fuels that are identical to their petroleum counterparts.
