Estimation of Middle Distillate Fuel Properties by FT-IR and Chemometrics. Part I. Calibrations and Validations.
Abstract
As an alternative to established laboratory protocols, an FT-IR method was developed for the rapid, simultaneous determination of several pertinent fuel properties, using less than 2 mL of sample. The method uses a single wavelength range of baseline uncorrected, raw FT-IR spectra. Neither baseline correction nor use of restricted wavelength regions improved the models. Using training sets comprised of over 500 middle distillate fuel samples, models were built to derive pertinent fuel properties from FT-IR spectra. These models showed that a single calibration training set may properly model several properties of fuels collected during different climatic seasons. Cursory experiments suggest that properties of diesel and turbine fuels may be more accurately derived by FT-IR if separate calibration models are used for each class of fuel.
