Characterization of petroleum heavy distillates using PHLC and spectroscopic methods

摘要

petroleum heavy distillates find wide application as feedstocks for upgradation through secondary conversion processes. Compositional data on such feedstocks provide useful information to the refiners for selecting processing parameters to achiever product selectivity, quality, and yield. AHPLC method has been optimized to estimate hydrocarbon group types in five lubricating oil base stocks using refractive index (RI) and UV detectors. Data generated at two wavelengths (210 and 254 nm) indicated best results for monoaromatics at 210 nm due to enhanced respones and compared well with mass spectrometry data.
