含磷加氢精制催化剂的研究进展

Progresses in Phosphorous Hydrotreating Catalysts

结合单金属、双金属和多金属3类加氢精制催化剂,详细论述了含磷的负载型和非负载型加氢催化剂的制备方法及其加氢性能,并将含磷加氢精制催化剂的加氢性能与传统的无磷加氢精制催化剂进行比较,指出含磷加氢精制催化剂的某些性能优于无磷加氢精制催化剂。有关负载型含磷加氢精制催化剂的研究多于其他含磷加氢精制催化剂,尤其是单金属和双金属催化剂。在磷是如何影响催化剂的加氢选择性和活性相的性质等方面还存在疑问,进一步探究各组分之间的作用机理、提高催化剂的加氢活性是今后的发展方向。

The preparation methods and hydrodesulfurization activity of supported and unsupported phosphorous hydrotreating catalysts,which could be divided into monometallic,bimetallic and multimetallic catalysts also,were discussed.Some performances of the phosphorus supported hydrotreating catalysts in the hydrodesulfurization were superior to those of traditional phosphorus-free hydrotreating catalysts.The researches about the supported phosphorous hydrotreating catalysts are more than those about other phosphorous hydrotreating catalysts,especially monometallic and bimetallic catalysts.How phosphorus affected the hydrogenation selectivity of the catalysts and the properties of the active phases was undetermined.The further researches about the interaction mechanism between every components and the improvement of the catalyst activity are prospective trends.
