The obtained materials were characterized by powder X-ray diffraction, transmission electron microscopy and N2 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 m2/g）. The mesoporous carbon was an excellent adsorbent to remove the refractory sulfur compound in diesel, especially dibenzothiophene and 4, 6-dimethyldibenzothiophene.展开更多
