MoS2 hydrodesulfurization catalyst was prepared by hydrothermal method. The resulting materials were characterized by BET, XRD, SEM and TEM. The influences of different surfactants on activity of catalyst were studied by measuring the hydrodesulfurization (HDS) of thiophene. The results showed that the catalyst particles with the addition of surfactants were loose, while the catalyst without the addition of surfactant exhibited serious agglomeration phenomenon. The surface area, pore volume, diameter and the number of the stacked layer of the catalysts with the addition of surfactants were much greater than those of catalysts without surfactants. The catalysts with surfactants showed high activity in the HDS of thiophene, the conversion of thiophene could reach to 97.0% at 573 K and 4. 0 Mpa pressure. Furthermore, the catalyst with the addition of cation surfactants showed the highest activity among these catalysts, and the conversion of thiophene was 99. 9%. By comparing the conversion, the reactivity order of the catalysts was: Mo-S-C>Mo-S-S>Mo-S-P>Mo-S-N.%采用水热法合成了MoS2加氢脱硫催化剂,用物理吸附、XRD、SEM、TEM等手段对催化剂进行表征,并以噻吩为模型化合物研究不同类型表面活性剂对合成MoS2催化剂活性的影响.结果表明,加入表面活性剂制备的催化剂颗粒疏松均匀,比表面积、孔容、孔径都较大,并且MoS2层状堆叠数目增加;所制催化剂在噻吩加氢脱硫反应中均显示出较好的催化活性,在573 K、4.0 MPa条件下,噻吩加氢脱硫的转化率均大于97.0％,加入阳离子表面活性剂的Mo-S-C催化活性最高,噻吩转化率可达到99.9％.MoS2催化剂的活性顺序为Mo-S-C＞Mo-S-S ＞Mo-S-P＞Mo-S-N.
