What is butanol?

Butanol is a four carbon alcohol. Alcohols are a family of chemical compounds that also inc(2-carbon) and propanol (3-carbon). Some of the more common uses for alcohol are alcohocommonly used for rubbing alcohol, chemical solvents - paint thinner and fuels. Initially, Band market butanol as a solvent, with the future intent of selling butanol as a fuel.

How is butanol manufactured?

ButylFuel, LLC has developed a process which makes fermentation derived butanol more competitive with current petrochemical processes and the production of ethanol. This econunder a federal DOE/STTR grant from the Department of Energy through the Small Busine

Butanol is presently manufactured from petroleum. Historically (early 1900s 1950s) biobcorn and molasses in a fermentation process that also produced acetone and ethanol and wabutanol, ethanol) fermentation. However, as demand for butanol increased, production by febecause the price of petroleum dropped below that of sugar when the USA lost its low-cost BFL has developed and patented a process which makes fermentation derived butanol morecompetitive with current petrochemical processes. (History of Butanol-1, 2, 3 )

What are the common uses of butanol?

Butanol is used primarily as an industrial solvent. The worldwide market is about 350 millimarket accounting for about 220 million gallons per year. Butanol currently sells for about and $6.80 in 55 gallon drums.

Butanol is also a replacement for gasoline as a fuel, to an even greater degree than ethanolproperties, economics, safety and the fact that it works without having to modify the engine

What are the technology possibilities behind butanol as an alternate fuel?

Advances in bio-technology have made it possible that corn and other biomass materials cabiobutanol derived by fermentation. Corn-to-butanol as a potential fuel source is just gainincorn-to-ethanol.

How does butanol compare with ethanol as an alternative fuel?

Butanol has many superior properties as an alternative fuel when compared to ethanol. The

Why has there been little to no effort to promote butanol as an alternate fuel?

Prior to the success of ButylFuel, LLCs work, production of butanol from corn and other black of technology to make it economically viable. The problem has been historically low ybiobutanol compared to those of bioethanol.

The historical ABE fermentation technology produces a variety of fermentation products. Tproduce Acetone Butanol and Ethanol. This fermentation process yielded a 6:3:1 ratio of Bu

That is, for each bushel of corn you would garner (1.3) gallons of butanol (0.7) gallons of aethanol with concentrations of 1-2%.

If you compared ABE yield to that of the yeast ethanol fermentation process, the yeast procfrom a bushel of corn, with concentrations of 10-15% it becomes very clear why ethanol wasource over butanol in the 1970's and 80's.

ButylFuel, LLC's patent changes everything. We are now able to produce yields of 2.5 gall

ButylFuel, LLC's patented discovery and the economics did not exist to pursue Butanol verto gasoline until now.

What does ButylFuel, LLC bring to the table when it comes to producing butanol?

ButylFuel, LLC has developed and patented technology that overcomes the limitations thatthe cost of butanol production from corn and other forms of biomass high. BFL is now ablefrom corn with no Acetone or Ethanol, whereas others have not been able to achieve better per bushel and still utilize an ABE process. Further, BFLs technology generates hydrogen additional attention as an alternative fuel in the future. In fact, taking into account the hydro42 % more energy from a bushel of corn than is typically produced by a corn-to-ethanol plawith the butanol and 18 % comes from the hydrogen.

What are the economics of the ButylFuel, LLC process?

This will not be known in detail until we complete testing on the Bu-100 (100 gallons butanmodel and the Bu-1,000 pilot plant. However, we can share the results of estimates we deveproceeding with these phases of the work.

Our preliminary cost estimates suggest that we can produce biobutanol from corn for aboutcredit for the hydrogen produced. This compares with ethanol production costs of about $1.the higher Btu content of butanol, this translates to 105,000 Btu per dollar for butanol and 8with corn at $2.50 per bushel. As a further point of reference, butanol produced from petrolto manufacture.

The economics of the ButylFuel, LLC process will be even more attractive when waste maof corn and the price to produce a gallon is $0.85 . In such cases the need and cost to grow a

Are there other benefits of ButylFuel, LLC technology?

Yes there are several.
