Abstract

The invention relates to a catalyst for isomerization of lubricating oil and a preparation method thereof. The catalyst is prepared from an organic alkali modified ZSM-48 molecular sieve, an organic alkali modified ZSM-5 molecular sieve, graphene oxide, an active metal component, aluminum oxide, an extrusion aid and an adhesive. The catalyst disclosed by the invention contains an organic alkali modified composite molecular sieve, so the content of n-alkanes in a product can be greatly reduced; and meanwhile, a viscosity index is greatly improved, which indicates that the catalyst disclosed bythe invention has the characteristics of good hydrogenation ring-opening performance and strong hydroisomerization capability, and can be used for producing high-quality lubricating oil in a hydrocracking petroleum refining process.

Description

technical field [0001] The invention relates to the technical field of catalysts, in particular to a catalyst for lubricating oil isomerization and a preparation method thereof. Background technique [0002] Hydrocracking technology has the characteristics of strong adaptability to raw materials, great flexibility in production operations and product plans, and good product quality. It can directly convert various heavy and low-quality feedstocks into high-quality jet fuel, diesel, and lubricating oil base materials that are urgently needed by the market. As well as chemical naphtha and tail oil steam cracking raw materials for ethylene production, it has become one of the most important heavy oil deep processing processes in modern oil refining and petrochemical industries, and has been increasingly widely used at home and abroad. [0003] The content of lubricating oil base oil in finished lubricating oil is usually 70%-99%, and the quality of base oil directly affects the...
