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
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.
