Fuel Quality Control by Mid Infrared Spectroscopy

Gasolines and diesel fuels of wide source were analyzed with the aim to predict the quality through the mid infrared spectroscopy and the algorithms PCA-PCR and PLS.

The results revealed that octane number, cetane number, MTBE, benzene, aromatics and specific gravity could be predicted with good reliability. The other relevant fuel physical-chemical characteristics were beyond the precision of the standard test methods.
