Claims20
A composition for fuel blending, comprising:
- (i) isobutanol;
- (ii) an octane improving component wherein the octane improving component is selected from the group consisting of high-octane aromatics, high-octane isoparaffins, alkylate, reformate, and combinations thereof;
- and
- (iii) a vapor pressure adjustment component 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, and combinations thereof.
1 more element
A composition for fuel blending, comprising:
- (i) from about 60 vol. % to about 90 vol. % of isobutanol, based on a total volume of the composition;
- (ii) from about 5 vol. % to about 35 vol. % of toluene, based on a total volume of the composition;
- and
- (iii) from about 5 vol. % to about 20 vol. % of n-butane, based on a total volume of the composition.
1 more element
A fuel blend comprising:
- (i) isobutanol;
- (ii) an octane improving component wherein the octane improving component is selected from the group consisting of high-octane aromatics, high-octane isoparaffins, alkylate, reformate, and combinations thereof;
- (iii) a vapor pressure adjustment component 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, and combinations thereof;
- and
- (iv) gasoline, a gasoline blend stock, or mixtures thereof;
- wherein the gasoline, gasoline blend stock, or mixtures thereof is formulated for the addition of ethanol.
