Soybeans and coconuts used to make aviation fuel to power jetsOctober 11th, 2008 - 2:47 pm ICT by ANI
Washington, Oct 11 (ANI): Scientists in the US have turned oil from plants like soybeans and coconuts into jet fuel that is equivalent to kerosene derived from oil.
According to a report in the Scientific American, working with the U.S. Department of Defenses Defense Advanced Research Projects Agency (DARPA), scientists at the Energy and Environmental Research Center (EERC) at the University of North Dakota turned these plant oils into fuel that had a similar density, energy content and even freezing point.
Its got a freeze point of 47 degrees Celsius (52.6 degrees Fahrenheit). Anyone familiar with biodiesel can tell you thats no small feat, said chemical engineer Chad Wocken, EERC environmental technologies research manager.
Its processed so that it contains only the same hydrocarbon molecules present in petroleum fuel, he added.
Wocken said that the process is thermocatalytic. In other words, the engineers heat the plant oils in the presence of an undisclosed catalyst to create a slew of petroleum products.
In fact, the process is not unlike conventional oil refining in that it produces everything from the kerosene used as aviation fuel to regular gasoline.
The processing costs would be similar and comparable to petroleum oil refining, and perhaps even less expensive, because youre not dealing with contaminants like sulfur, said Wocken.
Of course, the biofuels ultimate price tag is yet to be determined as only gallons of it have been brewed compared with the more than 60 million gallons (225 million liters) of jet fuel consumed daily in the U.S.
But, it will in large part depend on the price to grow the crops themselves. All have been fluctuating in recent months due to newly volatile global commodity markets.
Virgin Atlantic has flown a jumbo jet on a combination of conventional jet fuel and biofuel made from palm oil, and a jet powered solely by biodiesel has stayed aloft for more than 30 minutesalbeit with a special device to keep its fuel from freezing at high altitude.
The EERC is currently in the process of producing 25 gallons (95 liters) of the biojet fuel for ground testing in a jet engine as early as next month. (ANI)
