Adsorption Property of Cu-BTC for Dibenzothiophene Sulfide

Abstract:

Cu-BTC was synthesized by hydrothermal method. Adsorption desulfurization performance of Cu-BTC for dibenzothiophene sulfide was investigated. The adsorption property of Cu-BTC for dibenzothiophene and 4-methyldibenzothiophene in stimulated diesel were compared by equilibrium and dynamic experiments. The results show that when the equilibrium concentration is 0~50 mg S/L, the adsorption capacity of Cu-BTC for 4-methyldibenzothiophene is more than that of dibenzothiophene. When the equilibrium concentration is 50 mg S/L, the equilibrium adsorption capacity of Cu-BTC for 4-methyldibenzothiophene and dibenzothiophene are 17.54 mg S/g_ads and 15.64 mg S/g_ads, respectively. At the conditions of 30°C, 149.22h^-1 and 0.1MPa, the initial concentration of dibenzothiophene and 4-methyldibenzothiophene is about 45.16~46.36 mg S/L, the adsorption property of 4-methyldibenzothiophene is superior than dibenzothiophene, the breakthrough capacity of Cu-BTC for 4-methyldibenzothiophehe is 1.73 times lager than dibenzothiophene. Cu-BTC shows an excellent prospect on diesel desulfurization process.
