Determination-of-aromatic-hydrocarbons-in-diesel-fuel

INTRODUCTION

The aromatic hydrocarbons content of diesel fuel is a factor that can affect exhaust emissions and fuel combustion characteristics, as measured by cetane number. This application shows fast and robust method for the determination of monoaromatic, di-aromatic, and polyaromatic hydrocarbon contents in diesel fuels and petroleum distillates boiling in the range from 150 to 400 °C.

ABSTRACT

HPLC determination of aromatic hydrocarbon group types in diesel fuel and petroleum distillates boiling between 150 and 400 °C, on an ARION® NH2 5 µm column, 150 mm × 4.6 mm, part number ARI-5736-LK46. Mobile phase heptane, isocratic elution. Flow rate 0.8 mL/min, column temperature 30 °C, injection volume 10 µL, refractive index detection (RID). Analytes are reported as hydrocarbon classes rather than individual compounds, so no CAS numbers are given: 1. non-aromatic hydrocarbons (NAHs), 2. mono-aromatic hydrocarbons (MAHs), 3. di-aromatic hydrocarbons (DAHs), 4. polycyclic aromatic hydrocarbons (PAHs). The note shows a chromatogram of the calibration standard solution on the ARION® column, with the NAH, MAH and DAH peaks resolved between about 2.8 and 4 min and the PAH peak at…
