摘要： 自制介孔碳 (CMC) 具有比传统活性碳 (AC) 更大的比表面积、孔径和孔体积, 以其为载体, 在浸渍液中加入螯合剂, 采用等量浸渍法制备了 Co-Mo/CMC 和 Ni-Mo/CMC 催化剂, 分别用于模型汽油和柴油加氢脱硫反应. 结果表明, Co-Mo/CMC 和 Ni-Mo/CMC 催化剂具有比 Co-Mo/AC 催化剂更好的织构性质和加氢脱硫活性. 在模型汽油的加氢脱硫反应中, Co-Mo/CMC 催化剂活性比工业催化剂 Co-Mo/Al2O3 高得多; 而在模型柴油的加氢脱硫反应中, Ni-Mo/CMC 催化剂活性也比工业催化剂 FH-98 高得多.

Abstract: Mesoporous carbons (CMC) have larger average pore diameters and possess larger surface areas and pore volumes than traditional activated carbons (AC). Co-Mo/CMC and Ni-Mo/CMC catalysts were prepared by impregnation in the presence of a chelating agent and they exhibited much better porous properties than their AC supported counterparts. Accordingly, the CMC supported Co-Mo and Ni-Mo catalysts showed higher activities than the AC supported catalysts for the hydrodesulfurization (HDS) of organic sulfides. More importantly, Co-Mo/CMC was much more active than commercial Co-Mo/γ-Al2O3 for the HDS of thiophene in a model gasoline. Ni-Mo/CMC was sig-nificantly more active than commercial FH-98 for the HDS of dibenzothiophene in a model diesel.
