Abstract
Disclosed are methods and systems for manufacturing lubrication oils. In one embodiment, a method for manufacturing a lubrication oil includes the steps of receiving into an activated carbon guard bed unit an unconverted oil (UCO) feedstock, the UCO feedstock comprising polynuclear aromatic (PNA) compounds and contacting the UCO feedstock with activated carbon within the activated carbon guard bed unit to remove at least a portion of the PNA compounds, thereby forming a treated UCO feedstock.
