Carbon-based materials are a kind of promising sorbent for the desulfurization of fuel oils, especially for polycyclic aromatic sulfur heterocycles (PASHs), and development of new sorbents is of great significance. In this paper, six alkynyl carbon materials (ACM-1 to ACM-6) were prepared for the first time through mechanochemical reaction of calcium carbide with six full halogenated hydrocarbons, i.e., CCl4, C2Cl6, C2Cl4, C6Cl6, C6Br6, and C14H4Br10, respectively. Their carbon content and specific surface areas (SSAs) were analyzed, and their adsorption performance for thiophenic sulfurs was studied. The ACMs are mesoporous materials with relatively high SSAs and favorable adsorptive performance for PASHs with the order of DBT > BT > 3-MT. Their adsorptivity is virtually consistent with the SSA values and follows the order of ACM-6 > ACM-5 > ACM-4 > ACM-1 > ACM-3 > ACM-2. ACM-6 has the highest SSA (712 m2 g–1) and saturated adsorbance of 21.1 mg-S·g–1 for DBT in octane, as well as 6 mg-S·g–1 for real diesel. As a whole, ACM-6 represents the best ADS sorbent among all mesoporous carbon materials and may be applicable for real oils after some further modification.
