Methods are provided for refining natural oil feedstocks. The methods comprise reacting the feedstock in the presence of a metathesis catalyst under conditions sufficient to form a metathesized product comprising olefins and esters. In certain embodiments, the methods further comprise separating the olefins from the esters in the metathesized product. In certain embodiments, the methods further comprise hydrogenating the olefins under conditions sufficient to form a fuel composition. In certain embodiments, the methods further comprise transesterifying the esters in the presence of an alcohol to form a transesterified product.

Methods of refining natural oil feedstocks

Methods are provided for refining natural oil feedstocks and partially hydrogenating polyunsaturated olefins and polyunsaturated esters. The methods comprise reacting the feedstock in the presence of a metathesis catalyst under conditions sufficient to form a metathesized product comprising olefins and esters. In certain embodiments, the methods further comprise separating the polyunsaturated olefins from the polyunsaturated esters in the metathesized product. In certain embodiments, the methods further comprise partially hydrogenating the polyunsaturated olefins in the presence of a hydrogenation catalyst, wherein at least a portion of the polyunsaturated olefins are converted to monounsaturated olefins. In other embodiments, the methods further comprise partially hydrogenating the polyunsaturated esters in the presence of a hydrogenation catalyst, wherein at least a portion of the polyunsaturated esters are converted to monounsaturated esters.

Diene-selective hydrogenation of metathesis derived olefins and unsaturated esters

Systems and methods are disclosed for refining natural oil feedstocks. In some embodiments, the methods comprise transesterifying glycerides in a natural oil feedstock to provide a transesterified product comprising monounsaturated fatty acid esters and polyunsaturated fatty acid esters. In some embodiments, the methods comprise separating the polyunsaturated fatty acid esters from the monounsaturated fatty acid esters (or vice versa), to provide a separated monounsaturated fatty acid ester composition having a ratio of at least 10 parts by weight of monounsaturated fatty acid esters for every 1 part by weight of polyunsaturated fatty acid esters.

Systems and methods of refining natural oil feedstocks and derivatives thereof

Methods are provided for producing a jet fuel composition from a feedstock including a natural oil. The methods include 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 include hydrogenating the metathesized product under conditions sufficient to form a jet fuel composition.

Methods of producing jet fuel from natural oil feedstocks through metathesis reactions

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.

Methods are provided for refining natural oil feedstocks. The methods comprise reacting the feedstock with a low-molecular-weight olefin or mid-weight olefin in the presence of a metathesis catalyst under conditions sufficient to form a metathesized product comprising olefins and esters. In certain embodiments, the methods further comprise separating the olefins from the esters in the metathesized product. In certain embodiments, the methods further comprise transesterifying the esters in the presence of an alcohol to form a transesterified product.
