Abstract
Distillate feeds are hydroprocessed to produce a product having a low content of polyaromatic hydrocarbons (PAHs). The hydroprocessing includes dewaxing and aromatic saturation of the feed. The temperature of the aromatic saturation process can be controlled to make a distillate product having a desired aromatic content, such as less the 0.02 wt % of polyaromatic hydrocarbons having three or more aromatic rings.
