【摘要】 论述了柴油加氢脱除芳烃的催化剂体系、芳烃加氢反应机理和工艺方法。催化剂体系包括贵金属催化剂和非贵金属催化剂两种类型。其中贵金属催化剂的脱芳烃效果较非贵金属催化剂要好。柴油加氢脱芳烃大多采用两段加氢工艺,结合使用贵金属和非贵金属催化剂以取得良好的脱除芳烃效果。研究表明,载体性质对加氢脱芳烃催化剂的催化性能影响很大,新载体和新材料的开发是加氢脱芳烃催化剂研制的主要方向。更多还原

【Abstract】 A review about processes and catalysts for removal of aromatics contained in diesel oil is given The catalyst systems include noble metal and non-noble metal catalysts The hydro-dearomatization activities of noble metal catalysts are better than those of non-noble metal catalysts The mechanism of hydro-dearomatization is also discussed Techniques under developing such as two stage hydrotreating for diesel deep desulfurizing and dearomatizating using noble metal and non-noble metal as catalysts are widely used Latest advances in the materials and the carriers of hydrotreating catalysts show that the characters of carriers play an important role in the hydro-dearomatization catalysts The development of new carriers and materials is a research trend in hydro-dearomatization catalysts in the future更多还原
