Preparation of a kind of mesoporous carbon and its performance in adsorptive desulfurization

Carbon materials were prepared using mesoporous silica HMS with different pore sizes as the hard templates and water-soluble phenolic resin as the carbon source. The obtained materials were characterized by powder X-ray diffraction,transmission electron microscopy and N_2 physical adsorption,and were used in adsorptive desulfurization. It has been shown that the carbon material prepared using HMS with larger pore size (>3 nm) presented uniform wormlike mesopore of 2.3 nm and large BET surface area (1903 m~2/g). The mesoporous carbon was an excellent adsorbent to remove the refractory sulfur compound in diesel,especially dibenzothiophene and 4,6-dimethyldibenzothiophene.
