Abstract
Methods and systems for manufacturing lubrication oils are disclosed. In one embodiment, a method for manufacturing a lubrication oil includes the steps of receiving into an adsorber unit an unconverted oil (UCO) feedstock comprising five and six ring polynuclear aromatic (PNA) compounds and contacting the UCO feedstock with an adsorbent to remove PNA compounds, thereby forming a treated UCO feedstock with a low concentration of five and six ring PNAs.
