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. |
