| titleOfInvention | Method for preparing lubricating oil base oil by isomerization dewaxing-hydrorefining combined process |
| abstract | The present invention discloses a method for producing lubricating oil base oil by a combined isomerization dewaxing-hydrorefining process. The method includes an isomerization dewaxing process catalyzed by an isomerization dewaxing catalyst and a supplementary refining process using a hydrorefining catalyst. , wherein the isomerization dewaxing catalyst is a single-atom noble metal catalyst supported on a carrier, the refining catalyst is a single-atom noble metal catalyst supported on a carrier, and the carrier is selected from molecular sieve or alumina carrier; the noble metal is selected from platinum, One or more of palladium, ruthenium, rhodium, iridium, gold or silver. Since the single-atom catalyst has the characteristics that metal atoms are highly dispersed in the form of single atoms, and the atomic utilization rate reaches 100%, this method can achieve high-efficiency catalysis under the condition of lower noble metal usage, and achieve high-efficiency production of lubricating base oil while reducing noble metals. Usage amount. Using about 50% less precious metal than existing catalysts, the single-atomized catalyst still exhibits catalytic performance superior to current commercial nanocrystalline catalysts. |
