载体及改性方法对硫化型催化剂加氢性能的影响

通过在硅铝氧化物载体上添加第三组分Zr、B、P对载体进行改性,考察第三组分的种类及加入方式对载体性质的影响,结果表明,第三组分ZrO2的添加方式以络合添加最优,添加氧化锆的载体制备的催化剂活性金属分散最好,金属和载体间的作用力最适宜,用此载体制备的硫化型催化剂的加氢活性也最高.

Support and its Promoter Effecting on Performance of the Sulfided Catalysts

The article reveals the function of Zr, B and P as a third component added on the support of silica-alumina, and the ways of introduction of the third component effecting on the properties of the support. The results shows that introducing Zr on the support in chelating ways is the best, because it can make the active metals dispersed well on the surface of the catalyst, and can also produce superior mutual reactions between the support and active metal, which brings about better activities.
