Abstract

The effect of nitrogencontaining compounds acridine and 14dimethylcarbazole 14DMCARB on the hydrodesulfurization of 46dimethyldibenzothiophene 46DMDBT was studied on a sulfided NiMoP/Al2O3 catalyst in a fixed bed microreactor 340 °C 40 bar Both nitrogencontaining compounds inhibited the hydrodesulfurization of 46DMDBT However the effect of acridine a basic compound and mainly its hydrogenated product presumably 12345678octahydroacridine OHA1 was much more significant than the effect of 14DMCARB a nonbasic compound In the presence of acridine the socalled direct desulfurization pathway DDS of the HDS of 46DMDBT was less affected than the hydrogenation pathway HYD and was even slightly promoted when the partial pressure of acridine increased after a strong initial inhibition This was ascribed to a cocatalytic contribution of the nitrogencontaining compound to the C–S bond cleavage 14DMCARB had the same inhibiting effect on both pathways DDS and HYD We also demonstrated that acridine inhibited the transformation of 14DMCARB and can explain why carbazoles are generally the main nitrogen impurities present in gasole after hydrotreatment
