Effect of Mono-, Di-, and Triethylene Glycol on the Sulfidation Behavior of NiMo(P)/Al2O3 Hydrotreating Catalysts

The effect of ethylene glycol (EG), diethylene glycol (DEG), and triethylene glycol (TEG) on the sulfidation behavior of phosphate-doped NiMo/Al 2 O 3 hydrotreating catalysts has been investigated. The catalyst prepared with DEG shows a higher activity in the hydrodesulphurization of straight-run ga...

Description
Summary:The effect of ethylene glycol (EG), diethylene glycol (DEG), and triethylene glycol (TEG) on the sulfidation behavior of phosphate-doped NiMo/Al 2 O 3 hydrotreating catalysts has been investigated. The catalyst prepared with DEG shows a higher activity in the hydrodesulphurization of straight-run gas oil than other catalysts due to more efficient sulfidation at the low-temperature stage.
