深度加氢脱硫催化剂载体效应的研究进展

综述了近年来深度加氢脱硫催化剂载体的研究进展,主要介绍了单一氧化物载体、复合氧化物载体、酸性载体以及炭材料等其他载体对深度加氢脱硫催化剂活性的影响。单一氧化物载体容易与活性组分作用生成没有催化活性的相,从而影响催化剂的活性;复合氧化物载体可以克服单一氧化物载体的缺陷,从而使制备的催化剂对芳烃的加氢和对二苯并噻吩及它的芳烃衍生物的转化具有较好的效果;对芳香烃大分子硫化物的脱除,酸性载体比其他载体具有不可比拟的优势;炭材料等新型载体与金属活性组分的相互作用可达到最小,从而可以充分发挥金属活性组分的作用。

Advances of Research for Support Effect of Deep Hydrodesulfurization Catalyst

Developments in researches for supports of catalysts used in deep hydrodesulfurization of diesel oil,including oxide supports,composite oxide supports,acidic supports,carbon materials etc.,were summarized.Effects of the supports on catalyst activities in deep hydrodesulfurization were reviewed.Non-active phase could easily be produced by interaction between oxide supports and active metallic components in the catalysts,which lowered the catalyst activity.Composite oxide supports could overcome disadvantage of oxide supports,and were found to be very efficient in both hydrogenation of aromatics and conversions of dibenzo-thiophene and its alkyl-derivatives.Acidic supports had great advantage because of their ability to converse large molecules of aromatics in deep hydrodesulfurization.Additionally,carbon materials and other types of novel supports can decrease interaction between supports and active metallic components,so metallic components are able to fully sufficiently exert their effect.
