Examination of the hydrotreatment of light cycle oil over a dispersed MoS2 catalyst was conducted in a batch reactor at 375 degrees C and 1,500 psi. Hydrodesulfurization, hydrodenitrogenation, hydrogenation of aromatics, and hydrocracking activity were all analyzed. Diaromatics are more reactive than monoaromatics. Different sulfur compounds have experimental rates of elimination following the trend of BT>1MBT>> 2MBT>3MBT>4MBT>>DBT approximate to 1MDBT approximate to 2MDBT approximate to 3MDBT. BT and its derivatives are very reactive and easy to eliminate, but become harder to convert as they gain methyl groups. DBTs are harder to eliminate than BTs, and don't experience significant changes in reactivity as they gain methyl groups. This difference indicates that steric hindrance is more significant in supported catalysts than in unsupported catalysts. Different nitrogen compounds have experimental rates of elimination following the trend of Anilines> Indoles> Carbazoles.
