MoS_2是在催化剂领域、光化学领域以及润滑油领域都广受关注的材料。因其良好的加氢活性,通常在石油化工领域中作为加氢过程的催化剂活性组分。介绍了纳米MoS_2的插层剥离法、气相化学沉积法、前驱物分解法、水热合成法等多种合成方法,列举了不同方法合成MoS_2产品在形貌、大小、比表面积等方面的特点,并针对重油转化所需催化剂的特性对不同合成方法的优缺点进行了对比。最后简单介绍了意大利ENI公司以非负载MoS_2作为催化剂在浆态床加氢工业应用的实例。
MoS 2 is a widely recognized material in the field of catalysts, photochemistry and lubricants. Because of its good hydrogenation activity, it is generally used as a catalyst active component in hydrogenation processes in the petrochemical field. The synthesis methods of nano-MoS_2, such as intercalation and delamination, chemical vapor deposition, precursor decomposition and hydrothermal synthesis, were introduced. The characteristics of morphology, size and specific surface area of MoS_2 synthesized by different methods were introduced. The advantages and disadvantages of different synthetic methods were also compared against the characteristics of the catalyst needed for heavy oil conversion. Finally, an example of the industrial application of slurried bed hydrogenation by ENI Company of Italy with unsupported MoS_2 as catalyst is briefly introduced.
