Claims25
A cetane improver, the cetane improver comprising a non-oxygenated β-carotene.
A diesel fuel, the diesel fuel comprising a base fuel and a cetane improver, the cetane improver comprising non-oxygenated β-carotene and an alkyl nitrate.
A diesel fuel, the diesel fuel comprising a base fuel and a cetane improver, the cetane improver comprising non-oxygenated β-carotene.
A method of increasing a cetane number of a fuel, the method comprising:
- dissolving β-carotene in a diluent under an inert atmosphere to yield a cetane improver;
- and
- adding the cetane improver to a base fuel to yield an additized fuel, such that the cetane number of the additized fuel is higher than the cetane number of the base fuel.
