Oakbio produces n-butanol from CO2 and other waste carbon sources. N-butanol can be used both as a fuel or as a chemical feedstock. It has a current market size of approximately $10 billion/year. Oakbio’s n-butanol, produced from waste CO2, is 100% renewable.


n-butanol has several advantages over ethanol as a biofuel:

  • Higher energy content (105,000 BTU/gallon vs 84,000 BTU/gallon)
  • Easily blended
    • 87 Octane fuel can be a 100% replacement for gasoline
    • compatible with existing gasoline engines, pumps and storage infrastructure
    • less corrosive to engines
  • Less susceptible to separation
    • can be blended at the refinery
    • does not require separate distribution infrastructure
  • Lower emissions
    • lower vapor pressure reduces emitted hydrocarbons
    • produces less CO and NOx

Chemical Feedstock

n-butanol is primarily used as a feedstock for acrylics, paints, plastics, coatings, solvents and many other products. n-butanol is currently made from the petrochemical distillates. The advantages of Oakbio’s butanol are summarized below.
