Abstract

Molecular structures of petroleum fractions(diesel fuel, bunker-C oil, lubricant base stocks) have been analyzed and compared in terms of the compositions (aromatics, naphtherucs, paraffinics), aromatics(benzene-nuclear and bonded alkyl groups), C2(methylene) carbon atoms % <TEX>$C_{\alpha}$</TEX> and <TEX>$C_{\beta}$</TEX> carbon stom % in alkyl groups and paraffins(branched and normal) by near-infrared and <TEX>$^{13}C$</TEX>-NMR spectroscopy.
