Carbon Number Distribution of Paraffins, Naphthenes and Aromatics by GC

UOP 870 – Carbon Number Distribution of Paraffins, Naphthenes and Aromatics by GC

This is an automated method for determining the distribution of paraffins, naphthenes and aromatics by carbon number in hydrocarbon fractions having an endpoint of 200 C or less (C3-C11) (see NOTE). C12 paraffins and naphthenes at concentrations less than 3% can be determined. C9+ aromatics are reported as a group. Olefins, if present, are hydrogenated and the resultant saturates are included in the paraffin and naphthene distribution. The lower limit of detection for a single carbon number hydrocarbon type is 0.05 mass- or liquid volume (LV)-%.
