FOURIER TRANSFORM INFRARED (FTIR) CHEMOMETRIC METHOD TO DETERMINE CETANE NUMBER OF DIESEL FUELS CONTAINING FATTY ACID ALKYL ESTER ADDITIVES |
摘要 |
The present invention is a method to determine the cetane number of a diesel fuel containing a fatty acid alkyl ester including determining the infrared spectrum of the fuel and correlating the spectrum to the cetane number using a multivariate-based Mid-FTIR model. The fatty acid alkyl ester may be rapeseed methyl ester and the infrared spectrum includes the frequency ranges 4900-3500 cm<SUP>-1 </SUP>and 2200-1624 cm<SUP>-1 </SUP>or the frequency ranges 4900-3500 cm<SUP>-1 </SUP>2200-1800 cm<SUP>-1 </SUP>and 1700-1624 cm<SUP>-1</SUP>. |
