Claims
- 1. A fuel mixture comprising a hydrocarbon fuel and a yttrium ester/chelate complex, wherein when the hydrocarbon fuel is burned, V.sub.2 O.sub.5 is a by-product, and wherein the concentration of the yttrium complex in the mixture provides at least a stoichiometric amount of yttrium for a substantially complete reaction between the yttrium and V.sub.2 O.sub.5 whereby the yttrium and V.sub.2 O.sub.5 react to form YVO.sub.4.
- 2. The mixture of claim 1, wherein the concentration of the yttrium complex in the mixture provides at least 125% of the stoichiometric amount of yttrium required for a substantially complete reaction between the yttrium and vanadium.
- 3. The mixture of claim 1, wherein the yttrium ester comprises at least four carbon atoms and the chelating agent is hydrocarbon fuel soluble and that includes 2,4-pentanediene and the complex has a molar ratio of 2,4-pentanediene to yttrium of up to 5:1.
- 4. The mixture of claim 3, wherein the yttrium ester comprises four to twelve carbon atoms.
- 5. The mixture of claim 3, wherein the yttrium ester is selected from the group consisting of yttrium octonate and yttrium 2-ethyl hexanoate.
- 6. The mixture of claim 3, wherein the molar ratio of 2,4-pentanediene to yttrium is 2:1 to 3:1.
- 7. The mixture of claim 3, wherein the yttrium ester is selected from the group consisting of yttrium octonate and yttrium 2-ethyl hexanoate and the molar ratio of 2,4-pentanediene to yttrium is 2:1 to 3:1.
- 8. A hydrocarbon fuel soluble, water stable vanadium corrosion inhibitor yttrium ester chelate complex, comprising a yttrium ester having at least four carbon atoms and a hydrocarbon fuel soluble chelating agent that includes 2,4-pentanediene, wherein the complex has a molar ratio of 2,4-pentanediene to yttrium of up to 5:1.
- 9. The inhibitor of claim 8, wherein the yttrium ester comprises four to twelve carbon atoms.
- 10. The inhibitor of claim 8, wherein the yttrium ester is selected from the group consisting of yttrium octonate and yttrium 2-ethyl hexanoate.
- 11. The inhibitor of claim 8, wherein the molar ratio of 2,4-pentanediene to yttrium is 2:1 to 3:1.
- 12. The mixture of claim 9, wherein the molar ratio of 2,4-pentanediene to yttrium is 2:1 to 3:1.
- 13. The mixture of claim 10, wherein the molar ratio of 2,4-pentanediene to yttrium is 2:1 to 3:1.
