Abstract
Methods are provided for producing a jet fuel composition from a feedstock comprising a natural oil. The methods comprise reacting the feedstock with a low-weight olefin in the presence of a metathesis catalyst under conditions sufficient to form a metathesized product. The methods further comprise hydrogenating the metathesized product under conditions sufficient to form a jet fuel composition.
Claims20
A method of producing a jet fuel composition comprising:
- providing a feedstock comprising a natural oil;
- providing a low-weight olefin;
- reacting the feedstock with the low-weight olefin in the presence of a metathesis catalyst under conditions sufficient to form a metathesized product;
- and
- hydrogenating the metathesized product under conditions sufficient to form a jet fuel composition,
- wherein the jet fuel composition comprises hydrocarbons having a carbon number distribution between 5 and 16 carbon numbers.
