Abstract
A Ni–W loaded ETS-10/AlPO4-5/Al2O3 composite support catalyst was optimized and used in hydrodesulfurization (HDS) and hydrodearomatization (HDA) of Daqing FCC diesel feedstock. The result indicated that ETS-10 and AlPO4-5 showed positive synergism effect. The effects of operating conditions on its catalytic performance were investigated by using a 100mL hydrotreating test unit. The catalyst showed a remarkable HDS conversion of 99.9% and a HDA conversion of 73.2%. A clean diesel product with ultra-low sulfur content (<1.0μg/g) and very low polycyclic aromatic content (<2.0wt.%) was obtained.
