Abstract

Correlation between relative intensities observed in the FT-ICR MS spectra and each sulfur content, API gravity, Ca, V and TAN values were studied. 20 APPI negative mode spectra were used for the preliminary study. Relative intensities of each spectrum were normalized and peaks of the 20 spectra were aligned and combined to a single table. Many peaks having strong positive correlations (R value above 0.8) with TAN, Ca, V and sulfur contents were found. Most of the peaks correlating well with sulfur content belonged to either S, NxS or SOx class. The peaks with positive strong correlation with TAN had O2 group in their elemental formula. However, API gravity values showed relatively weaker correlation (maximum at around 0.6-0.7) with the observed peaks. Peaks having strong negative correlation with the properties were also found. N1 class compounds generally had negative correlation with TAN. The peaks in O1 group had strong negative correlation with sulfur content. More study is being conducted to evaluate the result and expanding the analysis with 20 APPI positive mode spectra.
