Abstract

As the quality of crude oil deteriorates and environmental regulations become increasingly stringent, the production of clean oil with ultra-low sulfur content is becoming increasingly urgent. At present, HDS is the most extensive technology for producing clean fuel oil. In this paper, MoS₄²- solution was successfully synthesized and used as precursor to prepare new sulfided NiMo/Al₂O₃hydrodesulfurization (HDS) catalysts. The catalyst was characterized by x-ray photoelectron spectroscopy (XPS) and high-resolution transmission electron microscopy (HRTEM) and assessed using the typical refractory 4,6-dimethyldibenzothiophene (4,6-DMDBT) as the model reactant. Results show that, compared with the conventional oxidized catalysts, the sulfided catalyst not only exhibits much higher sulfidation degree of Mo species, but also holds shorter and more suitable MoS₂ stacks, resulting in better HDS activity.
