Inhibitory Study for Joint Reactions of Hydrodesulfurization and Hydrodenitrogenation during Hydrotreating of Vacuum Gas Oil

Saba Ghani DA and Waleed Azez Jada’a

A set of hydro desulfurization experiments are carried out on vacuum gas oil in a trickle bed reactor to model the effect of inhibition on the joint reactions of hydro desulfurization, and hydro denitrogenation. Dibenzothiophene (DBT) is used as a model compound in vacuum gas oil. In absence of nitrogen compounds over the tested catalysts in a trickle bed reactor at (523 to 573 K), 1 to 3 hr-1, and a pressure range of 16 to 20 bar the results show an increase in conversion when temperature increases, a little positive effect on conversions when pressure increases, and a decrease in conversion when LHSV increases.
