The structure and properties of CAT-1 and CAT-2 catalysts were characterized by XRD, XRF, pyridine-IR, and N2 adsorption/desorption techniques. The hydrotreating tests with a lower initial boiling point light cycle oil from fluid catalytic cracking showed that CAT-1 catalyst achieved hydrodearomatization, hydrodesulfurization (HDS), and hydrodenitrogenation (HDN) performance: 97.4% hydrodesulfurization, 99.5% hydrodenitrogenation, 14 cetane number improvement, 97.6 wt % diesel yield, and 0.0410 g/cm3 density reduction. The high HDA activity of CAT-1 catalyst was attributed to a low total acidity and Lewis acidity. Adding various modified zeolites did not significantly influence HDS and HDN activities and diesel yield.
