Abstract
An unleaded gasoline composition comprises, based on the total volume of the unleaded gasoline composition, 50 to 96 vol. % of an unleaded gasoline; 2 to 20 vol. % of a mixed butanol; and 2 to 30 vol. % of a distillate oil fraction comprising a paraffin, an olefin, a naphthene, and an aromatic at an initial boiling point cut of 180° C., wherein the unleaded gasoline, the mixed butanol, and the distillate oil fraction are selected to provide the unleaded gasoline composition with a Research Octane Number of 90 to 101, determined in accordance with ASTM D 2699; and a Motor Octane Number of 81.4 to 90, determined in accordance with ASTM D 2700.
Claims17
An unleaded gasoline composition comprising:
- 50 to 96 vol. % of an unleaded gasoline, based on the total volume of the unleaded gasoline composition;
- 2 to 20 vol. % of a mixed butanol, based on the total volume of the unleaded gasoline composition, wherein the mixed butanol comprises two or more selected from the group consisting of sec-butanol, tert-butanol, n-butanol, and isobutanol;
- and
- 2 to 30 vol. %, based on the total volume of the unleaded gasoline composition, of a distillate oil fraction having an initial boiling point cut of 180° C. comprising a paraffin, an olefin, a naphthene, and an aromatic,
- wherein the unleaded gasoline, the mixed butanol, and the distillate oil fraction are selected to provide the unleaded gasoline composition with
- a Research Octane Number of 90 to 101, determined in accordance with ASTM D 2699;
- and
- a Motor Octane Number of 81.4 to 90, determined in accordance with ASTM D 2700;
- wherein the total volume of the unleaded gasoline composition is 100 vol. %.
A method for preparing an unleaded gasoline composition, comprising:
- combining 50 to 96 of an unleaded gasoline, based on the total volume of the unleaded gasoline composition;
- 2 to 20 vol. % of a mixed butanol, based on the total volume of the unleaded gasoline composition, wherein the mixed butanol comprises two or more selected from the group consisting of sec-butanol, tert-butanol, and isobutanol;
- and
- 2 to 30 vol. %, based on the total volume of the unleaded gasoline composition, of a distillate oil fraction having an initial boiling point cut of 180° C. comprising, a paraffin, an olefin, a naphthene, and an aromatic, wherein the unleaded gasoline, the mixed butanol, and the distillate oil fraction are selected to provide the unleaded gasoline composition with
- a Research Octane Number of 91 to 101, determined in accordance with ASTM D 2699;
- and
- a Motor Octane Number of 81.4 to 90, determined in accordance with ASTM D 2700;
- wherein the total volume of the unleaded gasoline composition is 100 vol %.
An octane-enhancing additive comprising 5 to 95 vol. % of a mixed butanol, wherein the mixed butanol comprises two or more selected from the group consisting of sec-butanol, tert-butanol, n-butanol, and isobutanol, and 5 to 95 vol % of a distillate oil fraction having an initial boiling point cut of 180° C. comprising a paraffin, an olefin, a naphthene, and an aromatic, based on the total volume of the octane-enhancing additive;
- wherein the total volume of the octane-enhancing additive is 100 vol. %.
