| titleOfInvention | Method for preparing polyolefin synthetic oil |
| abstract | The present invention relates to a method for preparing a polyolefin-based synthetic oil by cationic oligomerization of an olefin raw material, and can be used in the petrochemical industry. What has been developed is a step of preparing an olefin raw material, a step of preparing a solution and suspension of components of a catalyst system Al (O) -HCl-TBCh and putting it in a reactor, and a catalyst system Al (O)- Α-Olefin isomerization and higher olefin oligomerization under the action of HCl-TBCh and their combination, separating the spent catalyst, splitting the oligomerized product into fractions, and catalyst Pd And hydrogenating the fraction separated under the action of (0.2% by mass) / Al 2 O 3 + NaOH. The present invention improves all the steps of this devised method. In order to eliminate the corrosive activity of the product, the process further comprises the oligomerization product by using a metallic aluminum, triethylaluminum or KOH alcohol solution or by thermally dehydrochlorinating the chlorine-containing polyolefin with or without KOH. A step of dechlorinating the chlorine-containing oligoolefin present in In order to improve the technical and economic indicators of the process by increasing the yield of target fractions of polyolefins with kinematic viscosity at 100 ° C. of 2-8 cSt, the process further comprises Thermal depolymerization of a limited consumable high molecular weight polyolefin of 20 cSt to a target polyolefin of kinematic viscosity at 100 ° C. of 2-8 cSt. |
