Abstract

A pesticide or herbicide formulation comprising an effective amount of a pesticide or herbicide in a carrier or solvent fluid, wherein the carrier or solvent fluid comprises a Fischer-Tropsch hydrocarbon produced via Fischer-Tropsch conversion of synthesis gas. A method of producing a pesticide or herbicide formulation by combining an amount of an herbicide or pesticide and a biodegradable solvent to form a pesticide or herbicide solution. A method of producing a pesticide or herbicide formulation by converting synthesis gas into Fischer-Tropsch products in the presence of a Fischer-Tropsch catalyst and combining at least one Fischer-Tropsch product with a pesticide or herbicide to create the formulation.

Claims (33)

1 . A pesticide or herbicide formulation comprising an effective amount of a pesticide or herbicide in a carrier or solvent fluid, said carrier or solvent fluid comprising a Fischer-Tropsch hydrocarbon produced via Fischer-Tropsch conversion of synthesis gas.

2 . The formulation of claim 1 wherein the pesticide or herbicide is an agricultural formulation.

3 . The formulation of claim 1 wherein the pesticide or herbicide is an oil-soluble pesticide or herbicide.

4 . The formulation of claim 1 wherein the formulation is a concentrated form.

5 . The formulation of claim 1 comprising an inert solid carrier impregnated with a solution comprising the pesticide or herbicide and the FT hydrocarbon.

6 . The formulation of claim 5 wherein the solid carrier is selected from the group consisting of ground natural minerals, ground synthetic minerals, synthetic granules of inorganic and organic meals, granules of organic material, synthetic polymeric materials, and combinations thereof.

7 . The formulation of claim 1 wherein the formulation is in the form of an emulsifiable concentrate, and wherein the formulation comprises the effective amount of the pesticide or herbicide in FT hydrocarbon liquid carrier, and wherein the formulation further comprises an emulsifier.

8 . The formulation of claim 7 wherein the emulsifier is selected from the group consisting of surfactants.

9 . The formulation of claim 1 wherein the FT hydrocarbon comprises FT naphtha, FT diesel, FT kerosene or a combination thereof.

10 . The formulation of claim 1 wherein the Fischer-Tropsch hydrocarbon was produced with a precipitated iron catalyst comprising a weight ratio of potassium to iron in the range of from about 0.005 and about 0.015 and a weight ratio of copper to iron in the range of from about 0.005 and about 0.05.

11 . The formulation of claim 10 wherein the Fischer-Tropsch catalyst further comprises a structural promoter.

12 . The formulation of claim 11 wherein the structural promoter comprises silica.

13 . A method of producing a pesticide or herbicide formulation, the method comprising:

combining an amount of an herbicide or pesticide and a biodegradable solvent to form a pesticide or herbicide solution.

14 . The method of claim 13 wherein the biodegradable solvent is a product of Fischer-Tropsch conversion of synthesis gas.

15 . The method of claim 14 wherein the biodegradable solvent comprises Fischer-Tropsch diesel.

16 . The method of claim 14 wherein the biodegradable solvent comprises Fischer-Tropsch naphtha.

17 . The method of claim 16 wherein the biodegradable solvent comprises Fischer-Tropsch kerosene.

18 . The method of claim 14 wherein the biodegradable solvent is a product of Fischer-Tropsch conversion of synthesis gas in the presence of a precipitated iron catalyst.

19 . The method of claim 18 wherein the precipitated iron catalyst comprises a weight ratio of potassium to iron in the range of from about 0.005 and about 0.015 and a weight ratio of copper to iron in the range of from about 0.005 and about 0.05.

20 . The method of claim 13 further comprising impregnating a solid carrier with the solution.

21 . The method of claim 20 wherein the solid carrier is selected from the group consisting of ground natural minerals, ground synthetic minerals, synthetic granules of inorganic and organic meals, granules of organic material, synthetic polymeric materials, and combinations thereof.

22 . The method of claim 13 wherein the amount of pesticide or herbicide is a concentrated amount and wherein the solution further comprises an emulsifier, wherein the concentrated amount is an amount greater than an effective application amount of the pesticide or the herbicide.

23 . The method of claim 22 wherein the emulsifier is selected from the group consisting of surfactants.

24 . A method of producing a pesticide or herbicide formulation, the method comprising:

converting synthesis gas into Fischer-Tropsch products in the presence of a Fischer-Tropsch catalyst; and

combining at least one Fischer-Tropsch product with a pesticide or herbicide to create the formulation.

25 . The method of claim 24 wherein the FT catalyst is a precipitated iron catalyst comprising a weight ratio of potassium to iron in the range of from about 0.005 and about 0.015 and a weight ratio of copper to iron in the range of from about 0.005 and about 0.05.

26 . The method of claim 25 wherein the iron catalyst further comprises a structural promoter.

27 . The method of claim 26 wherein the structural promoter comprises silica.

28 . The method of claim 26 wherein the Fischer-Tropsch catalyst is a cobalt catalyst.

29 . The method of claim 24 further comprising upgrading the Fischer-Tropsch products.

30 . The method of claim 24 wherein the at least one Fischer-Tropsch product comprises naphtha, diesel, kerosene, or a combination thereof.
