Description

Technical Field

[0001] The invention belongs to the technical field of polymer production and separation, and relates to an electromagnetic rotary separation device for synthesizing poly-alpha-olefin. Background Art

[0002] Polyalphaolefin (PAO for short) is a synthetic base oil. Its raw materials mainly come from ethylene and propylene dispersed from gas or natural gas in crude oil, which are refined through complex chemical reactions such as polymerization and catalysis. It has the characteristics of high thermal oxidation stability, high viscosity index and good compatibility with mineral oil, and is one of the most commonly used base oils for synthetic lubricants. As a base oil, polyalphaolefin is widely used in the formulation of various high-grade and special lubricants, such as automotive engine oil, gear oil, hydraulic transmission oil, hydraulic oil, aviation engine oil and aviation lubricant. In addition, it can also be mixed with mineral oil in any proportion to meet the requirements for lubricant performance under different working conditions.

[0003] Poly-α-olefins are generally produced by directional polymerization of C8~10 α-olefins obtained by polymerization of ethylene with Lewis acid complex metal catalysts. The catalysts used are mainly metal catalysts with certain magnetism, such as Ni or Pd metal catalysts. In the poly-α-olefin synthesis system, due to the viscous physical properties of poly-α-olefins themselves, as the reaction proceeds, the metal catalyst gradually disperses unevenly in the viscous environment, and even under stirring conditions, there will still be problems of insufficient local reaction. Secondly, when the produced poly-α-olefins are discharged, the metal catalysts will be mixed with the poly-α-olefins and discharged together, so it is necessary to continuously add and replenish the metal catalysts, and it is also necessary to further process the poly-α-olefins to separate them from the metal catalysts, making the production process complicated.

When the power is turned off, the metal catalyst adsorbed on the electromagnetic rod 19 is thrown out with the rotation of the reactant and the action of centrifugal force, thereby improving the uniformity of the metal catalyst in the reactant, so that the uniformity of the distribution of the metal catalyst will not decrease due to the increase in product viscosity. When the driving gear 4 rotates, the turntable 20 is driven to rotate through the connection and cooperation of the connecting rod 9.
