BUTANOL as a FUELBUTANOL as a FUELBUTANOL as a FUELBUTANOL as a FUEL
it has a higher energy yield (C4)
can be readily integrated into existing fuel infrastructure
can be blended with petrol at all concentrations
can be blended with diesel
Can be used together with ethanol
(enhances the performance of ethanol fuel blends)

"Delivering solutions that reduce the world's reliance on fossil fuels is a global imperative. BiobutanolBiobutanol holds tremendous
potential for delivering solutions in the near term." - Charles O. Holliday, Jr., DuPont Chairman & CEO
“butanolbutanol is a next generation biofuel that will supersede ethanol and biodiesel as the biofuel of choice for road transportation within 10 years”
