Abstract

The invention relates to butanol compositions for fuel blending and fuel blends comprising such compositions. The compositions and fuel blends of the invention have desirable performance characteristics and can serve as alternatives to ethanol-containing fuel blends. The invention also relates to methods for producing such butanol compositions and fuel blends.

First claim

1 - 20 . (canceled)

21 . A composition for fuel blending, comprising:
(i) isobutanol, wherein the isobutanol is present in a concentration from about 0.01 vol. % to about 99 vol. % based on a total volume of the composition; (ii) an octane improving component; and (iii) a vapor pressure adjustment component.

22 . The composition of claim 21 , wherein the isobutanol is present in a concentration from about 0.1 vol. % to about 10 vol. % based on a total volume of the composition.

23 . The composition of claim 21 , wherein the isobutanol is present in a concentration from about 0.5 vol. % to about 10 vol. % based on a total volume of the composition.

24 . The composition of claim 21 , wherein the isobutanol is present in a concentration from about 1 vol. % to about 5 vol. % based on a total volume of the composition.

25 . The composition of claim 21 , wherein the octane improving component is selected from the group consisting of high-octane aromatics, high-octane isoparaffins, alkylate, reformate, ethanol, and combinations thereof.

26 . The composition of claim 21 , wherein the octane improving component is present in a concentration from about 1 vol. % to about 50 vol. % based on a total volume of the composition.

27 . The composition of claim 21 , wherein the octane improving component is present in a concentration from about 5 vol. % to about 35 vol. % based on a total volume of the composition.

28 . The composition of claim 21 , wherein the vapor pressure adjustment component is selected from the group consisting of n-butane, iso-butane, n-pentane, iso-pentane, mixed butanes, mixed pentanes, ethanol, isomerate, natural gas liquids, light catalytically-cracked naphtha, light hydrocracked naphtha, hydrotreated light catalytically-cracked naphtha, natural gasoline, and combinations thereof.

29 . The composition of claim 21 , wherein the vapor pressure adjustment component is present in a concentration from about 1 vol. % to about 30 vol. % based on a total volume of the composition.

30 . The composition of claim 21 , further comprising a driveability component, wherein the driveability component is selected from the group consisting of n-pentane, iso-pentane, 2,2-dimethyl butane, isomerate, hexanes, natural gas liquids, light catalytically-cracked naphtha, light hydrocracked naphtha, hydrotreated light catalytically-cracked naphtha, and combinations thereof.

31 . The composition of claim 21 , wherein the driveability component is present in a concentration from about 1 vol. % to about 30 vol. % based on a total volume of the composition.

32 . The composition of claim 21 , wherein the composition is for blending with a gasoline or blendstock for oxygenate blending (BOB), for terminal blending with a gasoline or BOB, or for splash-blending with a gasoline or BOB.

33 . A fuel blend comprising:
(i) isobutanol, wherein the isobutanol is present in a concentration from about 0.01 vol. % to about 99 vol. % based on a total volume of the composition; (ii) an octane improving component; (iii) a vapor pressure adjustment component; and (iv) gasoline, a gasoline blend stock, or mixtures thereof.

34 . The fuel blend of claim 33 , wherein the concentration of isobutanol is from about 0.1 vol. % to about 10 vol. % based on a total volume of the fuel blend.

35 . The fuel blend of claim 33 , wherein the isobutanol is present in a concentration from about 0.5 vol. % to about 10 vol. % based on a total volume of the fuel blend.

36 . The fuel blend of claim 33 , wherein the isobutanol is present in a concentration from about 1 vol. % to about 5 vol. % based on a total volume of the fuel blend.

37 . The fuel blend of claim 33 , wherein gasoline is conventional gasoline, oxygenated gasoline, reformulated gasoline, biogasoline, Fischer-Tropsch gasoline, or combination thereof.

38 . The fuel blend of claim 33 , wherein the concentration of gasoline or gasoline blend stock is from about 1 vol. % to about 99 vol. % based on a total volume of the fuel blend.

39 . The fuel blend of claim 33 , wherein the gasoline, gasoline blend stock, or mixtures thereof is formulated for the addition of ethanol.

40 . The fuel blend of claim 39 , wherein the gasoline, gasoline blend stock, or mixtures thereof is formulated for the addition of at least 10% ethanol.
