BioButanol Production Options ...
Scott Sklar discusses options for bio-production of butanol as an alternative to ethanol for blends with gasoline. ...
... "One company, Environmental Energy Inc. (EEI) has developed and patented technology that they believe overcomes the limitations that have to date kept the cost of butanol production from corn and other forms biomass high. EEI claims they
can produce 2.5 gallons of butanol from corn with no acetone or ethanol, whereas most other processes have not been able to achieve better than 1.3 to 1.9 gallons of butanol per bushel " ...
Via Renewable Energy Access: Why Isn't Butanol More Prevalent? ...
Via EEI: A Biomass-to-Butanol/Hydrogen Economy: "This process doubles the yield of butanol from a bushel of corn from 1.3 gallons per bushel to 2.5 gallons per bushel – matching the average ethanol yield that is generally achieved through ethanol fermentation. Since each process develops 2.5 gallons per bushel the process that converts sugars to butanol yields 24% more energy (Btu’s) per bushel. "
