This study focused on the molecular transformations of polycyclic aromatic and hydroaromatic hydrocarbons in hydroprocessing of vacuum gas oils. High performance liquid chromatography with UV diode array detection (HPLC-DAD) and field ionization mass spectrometry (FIMS) were used to elucidate the composition of hydroprocessed oils. Detailed compositional data reveal the presence of large polycyclic aromatic and cycloalkylaromatic species having up to eleven fused rings. Discovery of cycloalkyl-coronenes, having up to four naphthenic rings which are peri-fused to a coronene aromatic ring-core is of particular interest because these compounds are not native to petroleum. The molecular transformations leading to their formation are discussed.
