中文摘要：

在超声波作用下，采用单分子层剥离一重堆积技术，将正丁基锂柱插入MoS2夹层，合成了前驱体LixMoS2。前驱体和水反应，形成MoS2单分子层悬浮液，将其与Ni（NO3）2反应制得新型非负载型Ni—MoS2复合材料。XRD表征结果表明，Ni—MoS2复合材料呈硫化态。以抽余油催化加氢为探针反应，考察了Ni—MoS2复合材料在抽余油催化加氢制备特种溶剂油时的加氢脱硫（HDS）、加氢脱芳烃（HDAr）的活性。结果表明，抽余油催化加氢制备特种溶剂油的最佳条件为：Ni—MoS2复合材料中n（Ni）／n（Mo）=0．06，氢气分压6．0MPa，反应温度360℃，液时空速1．0h^-1。在此条件下，抽余油的HDS转化率为99．2％，HDAr转化率达到98．7％。

英文摘要：

Under the action of ultrasonic waves, the premonitory LixMoS2 was prepared by n-butyl lithium intercalating in MoS2 layers, by using the single-molecular-layer exfoliated-restacked technology. MoS2 single-molecular-layer suspension was formed by LixMoS2 reacted with water. The new-type unsupported Ni-MoS2 composite was obtained by the reaction of suspension with Ni（NO3）2 solution. The XRD analysis revealed that the Ni-MoS2 composite was in sulfide state. The catalytic hydrogenation of extract oil was used as probe reaction to investigate the catalytic activity of Ni-MoS2 composites for hydrodesulfurization （HDS） and hydrodearomatization （HDAr）. The results showed that optimum conditions for HDS and HDAr of extract oil were atomic ratio n（Ni）/n（Mo） in Ni-MoS2 composite of 0.06, hydrogen pressure of 6.0 MPa, reactive temperature of 360℃ and LHSV of 1. 0 h^-1, under which the HDS and HDAr conversion of extract oil was 99.2% and 98.7%, respectively.
