润滑油基础油加氢异构反应要求催化剂不仅要有合适的孔道结构和酸性分布，用于增强催化剂的异构重排能力，择形限制体积较大、裂化较快的双支链与三支链产物的形成，还要求其具有较高的加氢活性，避免反应产物在分子筛内部的二次裂化反应。因此，具有较小孔道结构和适宜酸性质载体的研制，是高性能润滑油基础油加氢异构催化剂开发的关键，同时，改善载体和活性金属之间的相互作用，提高催化剂加氢/脱氢能力也是新型高效润滑油基础油加氢异构催化剂开发研究所关注的热点问题。 The catalysts of hydroisomerization for lubricant base oil are required not only have a suitable pore structure and acidity distribution to enhance the ability of isomerization rearrangement, the shape-selective restrictions on the formation of di-branched and tri-branched products which have larger bulk and cracking faster, and the catalysts also need high hydrogenation activity, and to avoid secondary cracking reactions of the products in the internal of molecular sieves. Therefore, researching on the carrier of hydroisomerization catalysts which have smaller pore structure and appropriate acidity is the key to the development of high-performance lube base oil .At the same time, improving the interaction between the carrier and the active metal to improve the ability of hydrogenation / dehydrogenation is also the focus on the research of new efficient hydroisomerization catalyst for lubricant base oil. |

| It is required that the catalysts in hydroisomerization for lubricant base oil have not only suitable pore structures and acidity distribution to enhance the ability of isomerization rearrangement, the shape-selective restrictions on the formation of di-branched and tri-branched products which have larger bulk and cracking faster, but also high hydrogenation activity needed to avoid secondary cracking reactions of the products in the internal of molecular sieves. Therefore, it is the key for the development of high-performance lube base oil to research the carriers with relatively small pore structure and appropriate acidity for hydroisomerization catalysts. Meanwhile, it is also the focus on the research of new efficient hydroisomerization catalyst for lubricant base oil to improve the interaction between the carrier and the active metal for better abilities of hydrogenation and dehydrogenation. |
