NOVELTY - Producing fatty acid alkyl esters from greater than or equal to 2 sources comprises providing a triglyceride feed material of greater than or equal to 10 wt.% oleaginous seeds and unrefined vegetable oil and/or reclaimed oil containing glycerides of fatty acids with greater than or equal to 2 wt.% free fatty acids; extracting triglycerides and fatty acids with concurrent esterification of free fatty acids; adding 1-4C alkyl alcohol(s) and a base catalyst; forming fatty acid alkyl esters of the bound triglyceride fatty acids and the 1-4C alcohol and a glycerol by-product; washing the fatty acid alkyl esters; and purifying.    USE - Method of producing fatty acid alkyl esters from greater than or equal to 2 sources of triglycerides (claimed) for diesel fuel and non-fuel uses.    ADVANTAGE - The method produces fatty acid esters of lower alkyl alcohols from relatively low cost feedstocks. It has reduced investment overall for producing fatty acid esters for biodiesel fuel and chemical intermediates from vegetable seeds by charging the whole seeds directly to a reaction vessel for making the esters without the upstream seed crushing/oil refining operations. The method synergistically uses fractional distillation for the three-fold purpose of purifying the products, tailoring the composition of a biodiesel fraction, and supplying low-cost chemical intermediate(s). It can process a wide range of feed types with a high degree of free fatty acid conversion from seeds as well as waste oils.    DETAILED DESCRIPTION - Producing fatty acid alkyl esters from greater than or equal to 2 sources comprises    (A) providing a triglyceride feed material of greater than or equal to 10 wt.% oleaginous seeds and unrefined vegetable oil and/or reclaimed oil containing glycerides of fatty acids with greater than or equal to 2 wt.% free fatty acids;    (B) adding an acid catalyst (31) and 1-8C alkyl alcohol(s) to the triglyceride feed material to form a reaction mixture, where the alcohol is added in a molar excess relative to the free fatty acids in the triglyceride feed material;    (C) extracting triglycerides and fatty acids within the whole oleaginous seeds contained in the reaction mixture by heating the mixture to 60-150 degrees C;    (D) forming, concurrent with extracting, an ester of the alkyl alcohol and the free fatty acids in the reaction mixture by removing by-product water of reaction with a portion of the alkyl alcohol;    (E) adding 1-4C alkyl alcohol(s) and a base catalyst to form another reaction mixture, where the alcohol is in molar excess relative to fatty acids bound as triglycerides;    (F) forming fatty acid alkyl esters of the bound triglyceride fatty acids and the 1-4C alcohol and a glycerol by-product, by maintaining the reaction mixture at 50-80 degrees C;    (G) filtering all solids from product of the reaction mixture;    (H) washing the fatty acid alkyl esters by contacting with an aqueous solution followed by phase separation of an aqueous layer; and    (I) purifying the fatty acid alkyl esters by to meet standard biodiesel specifications.
