    Mesoporous carbon was prepared by loading four different metal ions Ag+/MC, Zn2+/MC, Cu2+/MC, and Fe3+/MC by impregnation method using mesoporous carbon (MC) as the carrier.The influence of the loading quality and the species of the metal ions on the adsorption were investigated.The results show that the adsorption capacity of two thiophene (DBT) can be improved by loading Ag+, Zn2+, Cu2+ and Fe3+ on the surface of mesoporous carbon.The optimum adsorption efficiency of mesoporous carbon with different metals is compared. The order of adsorption capacity of DBT is Ag+/MC>Zn2+/MC>Cu2+/MC>Fe3+/MC. Among them, the adsorption efficiency of loading 10% Ag+ on the mesoporous carbon is best. Compared with the untreated mesoporous carbon sulfur saturation capacity increases 1.11 mg/g, through the sulfur capacity also rises 1.93 mg/g.
