Popis: Detailed analytical description of the polycyclic aromatic structure distribution is useful for assessing the exact effects of refining processes, such as solvent extraction and hydrotreating, that alter or remove these compounds. High-resolution, low-voltage mass spectrometry was used to characterize the clay gel aromatics fractions of a petroleum vacuum distillate and three lubricant base oils that are derived from it. Proprietary methods were used to extract and hydrotreat the distillate, and different levels of severity were employed
