UOP to develop biofuel technology for military jets
UOP LLC, a Honeywell company, announced [*.pdf] today it will accelerate research and development on renewable energy technology to convert vegetable oils to military jet fuels. UOP developed a technique based on hydroprocessing that may yield fuels that meet the stringent requirements.
The goal of the project, which is backed by US$6.7 million in funding from the Defense Advanced Research Projects Agency (DARPA), is to develop and commercialize processes to produce a bio-based Jet Propellant 8 (JP-8) used by U.S. and NATO militaries.
Under the BAA, DARPA funds research and development efforts to develop a process that efficiently produces a surrogate for petroleum based military jet fuel - JP-8 (properties *.pdf) - from oil-rich crops produced by either agriculture or aquaculture (including but not limited to plants, algae, fungi, and bacteria) and which ultimately can be an affordable alternative to petroleum-derived JP-8. Approximately 4.5 billion gallons of JP-8 fuel are used by the U.S. Air Force, U.S. Army and NATO annually.
Current commercial processes for producing biodiesel such as transesterification (schematic, click to enlarge) yield a fuel that is unsuitable for military applications, which require higher energy density and a wide operating temperature range. Subsequent secondary processing of biodiesel is currently inefficient and results in bio-fuel JP-8 being prohibitively expensive.
The goal of DARPA's BioFuels program is therefor to enable an affordable alternative to petroleum-derived JP-8. The primary technical objective of the program is to achieve a 60% (or greater) conversion efficiency, by energy content, of crop oil to JP-8 surrogate and elucidate a path to 90% conversion:
bioenergy :: biofuels :: energy :: sustainability :: biodiesel :: vegetable oils :: bio-jet fuel :: biokerosene :: hydroprocessing :: JP-8 :: DARPA ::
Proposers were encouraged to consider process paths that minimize the use of external energy sources, which are adaptable to a range or blend of feedstock crop oils, and which produce process by-products that have ancillary manufacturing or industrial value. Current biodiesel alternative fuels are produced by transesterification of triglycerides extracted from agricultural crop oils. This process, while highly efficient, yields a blend of methyl esters (biodiesel) that is 25% lower in energy density than JP-8 and exhibits unacceptable cold-flow features at the lower extreme of the required JP-8 operating regime (-50F).
Potential approaches to produce a surrogate fuel for JP-8 may include thermal, catalytic, or enzymatic technologies or combinations of these. It is anticipated that the key technology developments needed to obtain the program goal will result from a cross-disciplinary approach spanning the fields of process chemistry and engineering, materials engineering, biotechnology, and propulsion system engineering. The key challenges are to develop and optimize process technologies to obtain a maximum conversion of crop oil to fuel.
JP-8 is a kerosene-based, high-performance fuel that is less flammable and less hazardous than other fuel options, allowing for better safety and combat survivability. In addition to jets, JP-8 is also used to fuel heaters, stoves, tanks, and other vehicles in military service. Commercial airliners use Jet A and Jet A-1, which is also kerosene-based.
UOP's process
UOP's bid was selected and the company will now work with Honeywell Aerospace, Cargill, Arizona State University, Sandia National Laboratories and Southwest Research Institute on the project, which is expected to be completed by the end of 2008. Fuel produced by the new process will have to meet stringent military specifications and is expected to achieve 90 percent energy efficiency for maximum conversion of feed to fuel, reduced waste and reduced production costs. UOP expects the technology will be viable for future use in the production of jet fuel for commercial jets.
UOP, formed its Renewable Energy & Chemicals business unit in late 2006 to commercialize solutions for production of renewable biofuel energy. At that time, UOP announced it has developed, along with European energy company Eni, a hydroprocessing technique to convert vegetable oils and waste into a high-cetane green diesel fuel with low emissions and high efficiency. The process, called UOP/Eni Ecofining, uses existing refinery infrastructure and technology. Earlier this month, UOP announced Eni will build the first Ecofining facility in Italy. The facility is projected to start up in early 2009 (earlier post).
DARPA is the central research and development organization for the Department of Defense (DoD). It manages and directs selected research and development projects for DoD for the advancement of military roles and missions. This is UOP’s first project with DARPA.
UOP LLC is a wholly-owned subsidiary of Honeywell International, Inc. and is part of Honeywell’s Specialty Materials strategic business group.

The focus of our renewable energy efforts has been to develop technologies that align with today’s standard refinery practices, but allow a broader range of feedstock options. We are confident that we have assembled a strong team of experts that will be successful in proving the viability of biofeedstock technologies for JP-8 and other jet fuels, while offering the U.S. military another option for sustainable liquid fuels critical to their programs. - Jennifer Holmgren, director of UOP’s Renewable Energy and Chemicals business unit.Bio-jet fuels, seen as the last biofuel frontier, have received a considerable amount of interest lately, with major aerospace manufacturers, airlines, biotech companies, universities, and governments (Argentina, US) participating in research to produce viable fuels for use in jet engines. Last year DARPA launched its BioFuels BAA (Broad Agency Announcement) aimed at exploring a wide range of energy alternatives and fuel efficiency efforts in a bid to reduce the military's reliance on oil to power its aircraft, ground vehicles and non-nuclear ships.
