A method for degumming and esterification of an oil comprising fatty acid glycerides, free fatty acids, and phospholipids comprises the steps of mixing the oil, a C1 to C5 monohydric alcohol, and methanesulfonic acid to form a reaction mixture, and heating the reaction mixture to esterify the free fatty acids and produce a fatty acid alkylester and water, and to degum the oil. The method further comprises the steps of causing a phase separation between a first phase comprising the C1 to C5 monohydric alcohol, phosphorous compounds, and water, a second phase comprising the fatty acid glycerides and the fatty acid alkylester, and a residual solid phase. Once the phase separation occurs, the second phase is separated from the first phase and the residual solid phase.

A method for treating a substrate prior to a metathesis reaction includes treating the substrate with a first agent configured to mitigate potentially adverse effects of one or more contaminants in the substrate on a catalyst used to catalyze the metathesis reaction. The treating reduces a level of the one or more contaminants by an amount sufficient to enable the metathesis reaction to proceed at a substrate-to-catalyst molar ratio of at least about 7,500 to 1. Methods for metathesizing substrates are described.

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.

The present invention relates to an improved process for the preparation of unsaturated fatty acids and to a process for the preparation of triglycerides with an increased content of unsaturated fatty acids. The invention relates to the generation of transgenic microorganism, with an increased content of fatty acids, oils or lipids with 6 double bonds owing to the expression of a moss 6-desaturase. The invention furthermore relates to transgenic organisms comprising a 6-desaturase gene, and to the use of unsaturated fatty acids ort of the triglycerides with an increased content if unsaturated fatty acids prepared in the process.
