A method for making a catalyst is provided that features loading a catalytic metal to a support using at least two different precursor compounds of that said metal; and loading the promoter to the support in an amount effective so as to achieve similar promotion as for a comparable catalyst comprising a greater amount of the promoter using only one precursor compound, where the catalytic metal is selected from among Group 8 metals, 9 metal, Group 10 metals, and combinations thereof. The promoter is preferably boron, silver, a noble metal, or combination thereof. Also provided are catalysts made by the method and Fischer-Tropsch processes that include contacting synthesis gas with a catalyst made by the method.

1. A process for the production of hydrocarbons comprising:contacting carbon monoxide and hydrogen with a synthesis catalyst so as to convert at least a portion of the carbon monoxide to the hydrocarbons, wherein the catalyst is made by a method comprising:(a) loading a Fischer-Tropsch metal to a porous support wherein the Fischer-Tropsch metal is in the form of at least a first precursor compound of the Fischer-Tropsch metal and a second precursor compound of the Fisher-Tropsch metal, wherein the first precursor compound and the second precursor compound are loaded separately; and(b) loading the promoter to the support in an amount effective so as to achieve similar performance of the catalyst as the performance of a comparable catalyst comprising a greater amount of the promoter and prepared by loading not more than one of the precursor compounds of the metal. 2. The process according to claim 1 wherein step (a) comprises selecting the precursors such that the portion of the metal loaded in the form of one of the first and second precursors is more easily reduced than the portion of the metal loaded in the form of the other of the first and second precursors. 3. The process according to claim 1 wherein at least a portion of step (b) is simultaneous with at least a portion of step (a) such that at least a portion of the promoter is loaded concurrently with at least a portion of the Fischer-Tropsch metal. 4. The process according to claim 1 wherein step (b) follows step (a). 5. The process according to claim 1 wherein step (b) precedes step (a). 6. The process according to claim 1 wherein the effective amount is not more than 75% of the content of promoter in the comparison catalyst. 7. The process according to claim 1 wherein the effective amount is not more than 50% of the content of promoter in the comparison catalyst. 8. The process according to claim 1 wherein the performance is selected from the group consisting of activity, stability, reducibility and selectivity. 9. The process according to claim 1 wherein the promoter is selected from the group consisting of rhenium, ruthenium, platinum, palladium, rhodium, copper, silver, rhodium, boron, gold, and combinations thereof. 10. The process according to claim 1 wherein the support is selected from the group consisting of alumina, modified alumina, silica-alumina, titania, zirconia, fluorided metal oxides, borated alumina, aluminum fluoride, aluminum boride, and combinations thereof. 11. The process according to claim 10 wherein the support is selected from the group consisting of alumina, modified alumina, and combinations thereof. 12. The process according to claim 11 wherein the support comprises at least 50% by weight alumina. 13. The process according to claim 12 wherein the support further comprises a second metal oxide. 14. The process according to claim 1 wherein the Fischer-Tropsch metal comprises cobalt. 15. A process for the production of hydrocarbons comprising:contacting carbon monoxide and hydrogen with a production catalyst so as to convert at least a portion of the carbon monoxide to the hydrocarbons,wherein the catalyst comprises a support comprising at least 50% alumina, cobalt, and a noble metal;wherein the catalyst is made by a method comprising:(a) loading the cobalt to the support as a first precursor compound and a second precursor compound, wherein the first precursor compound and the second precursor compound are loaded separately; and(b) loading the noble metal to the support; andwherein the non-gaseous hydrocarbon yield is similar to that of a comparable catalyst comprising cobalt and the noble metal, wherein the synthesis catalyst contains a lesser amount of the noble metal than does the comparison catalyst. 16. The process according to claim 15 wherein step (a) comprises selecting the precursors such that the portion of the metal loaded in the form of one of the first and second precursors is more easily reduced than the portion of the metal lo aded in the form of the other of the first and second precursors. 17. The process according to claim 15 wherein said catalyst further comprises boron. 18. The process according to claim 15 wherein at least a portion of step (b) is simultaneous with at least a portion of step (a) such that at least a portion of the promoter is loaded concurrently with at least a portion of the Fischer-Tropsch metal. 19. The process according to claim 15 wherein step (b) follows step (a). 20. The process according to claim 15 wherein step (b) precedes step (a). 21. The process according to claim 15 wherein the lesser amount is not more than 75% of the content of promoter in the comparison catalyst. 22. The process according to claim 15 wherein the lesser amount is not more than 50% of the content of promoter in the comparison catalyst.
