Effect of Operation Variables on Hydrodenitrogenation and Hydrodesulfurization over  NiMo/Al2O3 Catalysts

Abstract

Abstract: Using the JQ-Ⅱ high pressure hydrogenation micro-reactor unit, the reactivity of Athabasca
bitumen derived heavy gas oil was studied over commercial and homemade hydrotreating
catalysts. The effects of catalyst preparation variables and the influences of operation
conditions, such as pressure, temperature, hydrogen/oil ratio and space velocity were also
examined. It was shown that the optimal concentrations of the active components were 5% of
NiO, 20% of MoO3 and 3.5% of phosphorus (by mass), and the suitable operation conditions
were determined experimentally.

Key words: hydrotreatment, heavy gas oil, hydrodesulfurization, hydrodenitrogenation
