摘要：

Fourier-transform (FT) Raman data were obtained, from a series of gas oil samples, by using a 1.064-µm laser source. These were analyzed with a proprietry multivariate software package (CIRCOM) to obtain a correlation between the spectral changes and fuel quality (cetane number and cetane index). The correlation coefficient (r2), between the FT Raman data and cetane index, was 0.93, with a standard error of estimate (SEE) and standard error of prediction (SEP) of 1.13 and 1.22 cetane units, respectively. In addition, the chemical information relating to fuel quality was elucidated which agreed well with that previously understood. © 1990, American Chemical Society. All rights reserved.
