Combustion catalyst carriers and methods of using the same
Compositions including an iron containing fuel additive and a solid carrier are disclosed. Methods of preparing tablet forms of the compositions are also disclosed. The iron containing fuel additive may be ferrocene and/or substituted ferrocene derivatives. The compositions are useful for handling and rapidly solvating the iron containing fuel additive in a fuel such as gasoline.
1. A composition comprising:
(a) a fuel soluble ferrocene compound; and
(b) a fuel soluble solid carrier selected from biphenyl.
2. The composition according to claim 1 , wherein the fuel soluble ferrocene compound is selected from one or more compounds of the formula:
wherein each of R and R′ are independently selected from hydrogen, alkyl, cycloalkyl, aryl, alkylene, alkoxy, ketone, ester, aldehyde, amide, hydroxyalkyl, or heterocyclic.
3. The composition according to claim 2 , wherein the fuel soluble ferrocene compound is unsubstituted ferrocene.
4. The composition according to claim 2 , wherein the fuel soluble ferrocene compound is a substituted ferrocene.
5. The composition according to claim 2 , further comprising one or more additional fuel soluble ferrocene compounds.
6. A method of preparing a fuel additive comprising:
combining a fuel soluble ferrocene compound and a fuel soluble solid carrier selected from biphenyl.
7. The method according to claim 6 , wherein the fuel soluble ferrocene compound is unsubstituted ferrocene.
8. A method of supplementing a fuel comprising:
adding a fuel additive composition to the fuel, the fuel additive composition comprising:
(a) a fuel soluble ferrocene compound; and
(b) a fuel soluble solid carrier selected from biphenyl.
9. The method according to claim 8 , wherein the fuel soluble
ferrocene compound is selected from one or more compounds of the formula:

10. The method according to claim 9 , wherein the fuel soluble ferrocene compound is unsubstituted ferrocene.
11. The method according to claim 9 , wherein the fuel soluble ferrocene compound is a substituted ferrocene.
12. The method according to claim 8 , further comprising one or more additional ferrocene compounds.
13. The method of claim 9 , wherein the composition is in the form of a tablet.
14. A composition consisting essentially of:
(a) a fuel soluble ferrocene compound; and
(b) a fuel soluble solid carrier selected from biphenyl.
