中文摘要：
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.
英文摘要：
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 significantly more active than commercial FH-98 for the HDS of dibenzothiophene in a model diesel.
