Abstract
A method for characterization of petroleum fractions (220/sup 0/C-500/sup 0/C) is presented. The structural characteristic and the paraffinic and aromatic hydrocarbon content are determined on the basis of the /sup 1/H NMR spectral data and boiling range data. The method is tested on middle fractions (220/sup 0/C-390/sup 0/C), as well as on a number of Yugoslav and imported samples with wider boiling range and higher boiling points (up to 500/sup 0/C). The aromatic carbon content was compared with the results obtained by the IR method. The aromatic and paraffinic hydrocarbon content was compared with the results obtained by ASTM D-1319-70 and D-2549-68. The standard deviation and the difference of the average for the results obtained by the NMR method were computed, as opposed to the results of the forementioned referent methods.
