| titleOfInvention | A method for preparing polyalphaolefin synthetic lubricating oil base oil |
| abstract | The invention relates to a method for preparing polyalpha-olefin synthetic lubricating oil base oil in the technical field of lubricating oil base oil preparation. The method comprises the following steps: S1, adding long-chain α-olefins, main catalyst and co-catalyst into the reactor, then heating up to reaction temperature to obtain a mixture of catalyst and long-chain α-olefins at the reaction temperature; S2, adding short-chain α-olefins Chain α-olefins are added dropwise to the mixture of catalyst and long-chain α-olefins at the reaction temperature to react to obtain a solution after the reaction; S3, to terminate the reaction on the reacted solution to obtain poly-α-olefin synthetic lubricating oil base oil. The method has high catalytic activity and selectivity of oligomerization products containing more than 30 carbon atoms, and realizes the purpose of increasing the effective component content of lubricating oil base oil. |
