DuPont and BP: Biobutanol Blending at Higher Level Than Ethanol Won't Hurt Performance

NEW YORK (AP) -- EI DuPont de Nemours & Co. and BP PLC said Thursday that their testing of renewable fuel component biobutanol has shown that it can be blended with gasoline at a higher proportion than ethanol without hurting fuel performance.

DuPont and BP said they were able to create a fuel blend with a 16 percent concentration of biobutanol. Ethanol is generally blended at 10 percent.

BP performed testing on fuel formulation and short-term engine performance, as well as long-term, no-harm and durability tests over the past year. Results showed "comparable" results to regular gasoline, and the biobutanol did not "phase separate," or form two solutions, in the presence of water. Ethanol has a tendency to phase separate, which can cause engine damage over long periods of time.

BP and DuPont are each contributing $18 million toward a biobutanol research facility in Hull, northern England. The facility will use wheat as a primary feedstock, but also consider corn, rye and barley as possible fuel sources.

BP, DuPont and Associated British Foods PLC have agreed to develop a $400 million bioethanol plant at the Hull location as well. BP, a major integrated oil company, is seeking alternative fuels. DuPont, a science and technology company, has been at the forefront of such research, while Associated British Foods is involved with the agricultural components.

DuPont shares rose 17 cents to $46.83 in morning trading as BP rose 13 cents to $66.89.
