Oak Ridge says it has less costly biodiesel process

A new material developed at the U.S. Department of Energy’s Oak Ridge National Laboratory might replace a costly process in biodiesel production. Scientists at the laboratory’s Nanoscience Center say the technology might replace the biodiesel manufacturing process that consumes chemicals, water and energy and also reduces the yield of the final product. During production, catalysts must be applied to transform biodiesel from a thick and sticky substance into a fluid that can easily be pumped into vehicles. Following that process, the corrosive catalysts must be neutralized and washed from the fuel. (March 21, 2007)
