Abstract
The present invention relates generally to a composition and method for increasing the amount of cetane in fuel. More specifically, it was discovered that the amount of cetane in fuel can be increased by mixing a fuel additive comprising β-carotene that was prepared in an inert atmosphere.
Claims58
A hydrocarbon fuel comprising a base fuel and a non-oxygenated cetane improver additive selected from the group consisting of a precursor of carotene, a precursor of carotenoid, a derivative of carotene, a derivative of carotenoid and mixtures thereof.
A method of increasing a cetane number of a fuel, the method comprising dissolving a non-oxygenated additive in a diluent under an inert atmosphere to yield a cetane improver, the additive being selected from the group consisting of a precursor of carotene, a precursor of a carotenoid, a derivative of carotene, a derivative of carotenoid and mixtures thereof;
- and adding the cetane improver to a base fuel to yield an additized fuel, such that the additized fuel has a cetane number higher than the cetane number of the base fuel.
A hydrocarbon fuel comprising a base fuel and a non-oxygenated cetane improver additive, the additive selected from the group consisting of α-carotene or carotenoids derived from algae xea xabthin, crypotoxanthin, lycopene, lutein, precursors of α-carotene or carotenoids derived from algae xea xabthin, crypotoxanthin, lycopene, lutein;
- derivative of α-carotene or carotenoids derived from algae xea xabthin, crypotoxanthin, lycopene, lutein and mixtures thereof.
A hydrocarbon fuel comprising a base fuel and a non-oxygenated cetane improver additive the additive selected from the group consisting of a carotenoid derived from broccoli concentrate, spinach concentrate, tomato concentrate, kale concentrate, cabbage concentrate, and brussel sprout extract and mixtures thereof.
