Abstract

The invention relates to a method for removing impurities from fatty acid methyl esters based on natural fats and oils, especially for separating glycerine and traces of alkali metal compounds. As a result of the disadvantages of prior art, the aim of the invention is to produce a method by which means impurities such as glycerine and traces of alkali metal compounds are approximately completely removed from fatty acid methyl esters based on natural fats and oils, with relatively simple means. To this end: a) the FAME raw product is treated with a neutralisation means that is insoluble in the raw product in order to remove the transesterification catalyst, b) methanol is then removed by distillation, and c) the methanol-free FAME raw product is brought into contact at least once with phosphorylated and carbamated starch phosphate particles, the glycerine contained in the FAME raw product being absorbed by the starch phosphate particles. The cited starch phosphate particles can absorb up to ten times the quantity of their own weight in glycerine from biodiesel and therefore achieve a maximum residual content of glycerine of 0.02 %.
