Additives for improving autoignition reactivity of hydrocarbon-based fuels
| DWPI Title: New 1-nitropentane derivative additive for for hydrocarbon-based fuel used in fuel composition |
| Abstract: According to various aspects, an additive for a hydrocarbon-based fuel has a formula (I), in which R1, R2, and R3 are each independently selected from —H, —CH3, or —CH2CH3, and at least one of R1, R2, or R3 is not —H. The additive improves an autoignition reactivity of the hydrocarbon-based fuel. The additive can be present in the fuel composition including the additive and the hydrocarbon-based fuel in an amount of 0.1% by volume to 5% by volume. The hydrocarbon-based fuel can comprise gasoline or diesel. |
| Use: 1-nitropentane derivative additive (I) for hydrocarbon-based fuel used in fuel composition (claimed). |
| Advantage: The 1-nitropentane derivative additive (I) improves the autoignition reactivity of a hydrocarbon-based fuel composition, exhibits greater efficacy than conventional reactivity improving additives (such as 2-ethylhexyl nitrate), thereby enabling a reduction in the amount of additive needed to achieve a specific cetane number (CN) or research octane number (RON), and leads to less engine nitrogen oxide (NOx ) emissions as compared to fuel compositions containing conventional reactivity improving additives. |
| Novelty: 1-nitropentane derivative additive (I) is new. |
