活性金属不同浸渍顺序对Mo-Ni/Al2O3催化剂硫醚化反应性能的影响
Effect of impregnation sequence of Mo and Ni on the performance of Mo-Ni/Al2O3 catalyst in thioetherification
摘要
Abstract
Mo-Ni/Al2O3 catalysts were prepared by different impregnation sequences of Mo and Ni;the effect of impregnation sequence on the performance of Mo-Ni/Al2O3 catalysts in thioetherification was investigated.The results showed that the activity of the catalyst obtained by first impregnating Mo and then Ni (SI-mn) is close to that prepared by co-impregnation of Mo and Ni (MN);both are much more active than the catalyst obtained by first impregnating Ni and then Mo (SI-nm).For the SI-mn catalyst,Mo loaded on Al2O3 at the first stage can weaken the interaction between Ni and supporter,leading to a strong electronic effect between Ni and Mo,which can promote the formation of active phase in the presulfidation process and then enhance the catalytic performance of Mo-Ni/Al2O3 in thioetherification and selective hydrogenation of diene.Similar phenomena are observed for the MN catalyst obtained by co-impregnation,which also exhibits high activity in thioetherification.关键词
