Fuel components, fuel compositions and methods of making and using same
View Patent ↗A fuel composition comprises at least a C 5 isoprenoid compound or its derivative and a conventional fuel additive. The C 5 isoprenoid compound or its derivative can be used as a fuel component or as a fuel additive in the fuel composition. The fuel composition may further comprise a conventional fuel component selected from a diesel fuel, jet fuel, kerosene or gasoline. Methods of making and using the fuel composition are also disclosed.
1. A fuel composition comprising or obtainable from a mixture comprising:
(a) a C 5 isoprenoid compound of formula (Ib) or (Ic):
wherein Z is O—R, O—C(═O)R, O—PO(OR) 2 , O—SO 2 —OR, PO(OR) 2 or SO 2 —OR; and R is H, alkyl, cycloalkyl, aryl, alkaryl or aralkyl; and
(b) a fuel additive.
2. The fuel composition of claim 1 , wherein the amount of the C 5 isoprenoid compound is from about 1% to about 95% by weight or volume, based on the total weight or volume of the fuel composition.
3. The fuel composition of claim 1 , wherein Z of formula (Ib) or (Ic) is OH.
4. The fuel composition of claim 1 , wherein the C 5 isoprenoid compound is according to formula (Ib).
5. The fuel composition of claim 4 , wherein Z is OH.
6. The fuel composition of claim 1 , wherein the C 5 isoprenoid compound is according to formula (Ib).
7. The fuel composition of claim 6 , wherein Z is OH.
8. The fuel composition of claim 3 , wherein the fuel composition is substantially free of a second alcohol, wherein the second alcohol is not 3-methyl-3-buten-1-ol, 3-methyl-2-buten-1-ol or a combination thereof.
9. The fuel composition of claim 8 , wherein the second alcohol is methanol, ethanol, n-propanol, iso-propanol, n-butanol, iso-butanol, tert-butanol, n-pentanol, sec-pentanol, tert-pentanol, n-hexanol, iso-hexanol, sec-hexanol, tert-hexanol, heptanols, octanols, nonanols, decanols or a combination thereof.
10. The fuel composition of claim 1 , wherein the fuel composition is substantially free of an aromatic compound.
11. The fuel composition of claim 1 further comprising a petroleum-based fuel in an amount from about 1% to about 95% by weight or volume, based on the total weight or volume of the fuel composition.
12. The fuel composition of claim 11 , wherein the petroleum-based fuel is gasoline.
13. The fuel composition of claim 12 wherein the C 5 isoprenoid compound is according to formula (Ib) and Z is OH and the C 5 isoprenoid compound is present in an amount from about 1% to about 12.5% by volume, based on the total volume of the fuel composition.
14. The fuel composition of claim 1 , wherein the fuel additive is selected from the group consisting of oxygenates, antioxidants, thermal stability improvers, cetane improvers, stabilizers, cold flow improvers, combustion improvers, anti-foams, anti-haze additives, corrosion inhibitors, lubricity improvers, icing inhibitors, injector cleanliness additives, smoke suppressants, drag reducing additives, metal deactivators, dispersants, detergents, demulsifiers, dyes, markers, static dissipaters, biocides and combinations thereof.
15. The fuel composition of claim 1 , wherein the amount of the fuel additive is from about 0.1% to about 20% by weight or volume, based on the total weight or volume of the fuel composition.
16. A fuel composition made by a method comprising the steps of:
(a) contacting a cell capable of making a C 5 isoprenoid compound of formula (Ib) or (Ic):
wherein Z is OH with a simple sugar under conditions suitable for making the C 5 isoprenoid compound; and
(b) mixing the C 5 isoprenoid compound with one or more fuel components or fuel additives to make the fuel composition.
17. A fuel composition comprising a fuel component and a bioengineered C 5 isoprenoid compound.
18. A fuel composition produced by preparing 3-methyl-3-buten-1-ol from a mixture comprising a microorganism, and incorporating the 3-methyl-3-buten-1-ol in a fuel.
19. The fuel composition of claim 18 , wherein the mixture further comprises a simple sugar.
20. The fuel composition of claim 19 , wherein the simple sugar is glucose, galactose, mannose, fructose, ribose or a combination thereof.
