摘要
综述了载体、活性组分及助剂、催化剂的制备方法等因素对加氢脱硫催化剂活性的影响。在加氢脱硫催化剂制备过程中,选用介孔材料作为载体,其不仅具有高比表面积,且孔径较大,对深度加氢脱硫中芳香大分子硫化物的脱除具有不可比拟的优势;过渡金属磷化物被认为是一种高活性、高稳定性和具有抗硫中毒性能的新型催化材料;助剂的引入,有利于催化剂的制备和改善催化性能;浸渍法是国内外制备负载型催化剂的广泛应用的方法,而超声波-微波法可在催化剂表面形成纳米级的活性结构,可制备出高分散度、高活性的催化剂。
The effect of the factors like carrier, active component, promoter and catalyst preparation meth- ods, etc. on the activity of HDS catalyst was summarized. A mesoporous material was used as the carrier for the preparation of HDS catalyst. This mesoporous material has high specific surface area and large pore size, and therefore has incomparable advantage in removing large molecule aromatic sulfur -containing sulfides in deep hydrodesulfurization process. Metal phosphide is a new material for the preparation of catalyst, and it has high activity, high stability and good sulfur poisoning resisting property. The use of promoter is beneficial to the preparation of catalyst and the improvement of catalytic performance. While impregnation method is a widely used method for preparing supported catalyst, supersonic - microwave method can create an active structure of nanoscale on the surface of catalyst and prepare a catalyst with high dispersion degree and high activity.
