Abstract

Sulfur containing compounds of oil cuts cause air pollution, corrosion of metallic equipments and refinery catalysts poisoning, so using Hydrodesulfurization (HDS) catalysts and reducing sulfur content of oil cuts is critical. These catalysts generally contain a uniform monolayer dispersion of VIB group metal oxides such as MOLYBDENUM oxide and VIII group metal oxides such as COBALT oxide on a carrier preferably G-ALUMINA. In this work successive dry IMPREGNATION of G-ALUMINA by ammonium heptamolybdate and COBALT nitrate solutions was used to prepare HDS catalyst samples and then effect of IMPREGNATION solution pH. Mo and Co solution concentration, drying rate and feed flow rate on the Hydrodesulfurization performance was investigated. The samples were evaluated via scanning electron microscopy, porosimetery and reactor tests. The catalyst sample JDS-C5 shows the ability of reducing sulfur content of the feed from 1200 ppm to less than 1 ppm in the refinery HDS unit operation conditions (T=290 °C and P=15 bar).
