Quantitative Analysis of FAME (Fatty Acid Methyl Ester) in Diesel Fuel by FTIR

FAME (fatty acid methyl ester) has numerous advantages, as it does not form sulfur oxides (SOx) when burned, can be mixed with petroleum at arbitrary ratios, and has a high flash point and lubricating ability. Standardization of FAME has been studied in Japan referring to European standards, and the upper limit of FAME that can be mixed with diesel fuel was set at 5 wt%. This article introduces a quantitative analysis method for FAME in diesel fuel by the transmission method of the Fourier transform infrared spectrometer (FTIR).
