FATTY ACID BLENDS AND USES THEREFOR IN FUEL

摘要

A mixture of fatty acid alkyl esters that comprises: (i) At least 50 percent by weight of saturated medium chain fatty acid alkyl esters that have 6-14 carbons, myristoleic acid alkyl ester and monosaturated long chain fatty acid alkyl esters having more than 18 carbons; and (ii) Less than 10 percent by weight myristic acid alkyl ester and saturated long chain acid alkyl esters. The mixture comprises either (1) lauric acid alkyl ester (C12:0) at 5 to 20 percent by weight of the mixture or (2) the mixture comprises 15 to 40 percent fatty acid alkyl esters having 6-14 carbons and 60 to 85 percent monosaturated fatty acid alkyl esters having more than 18 carbons. The mixture can be used as a fuel for an internal combustion engine; in particular the mixture is used in a biodiesel blend.
