Abstract
The invention discloses a micro-interface strengthening reaction system for preparing poly-α-olefin, which includes: a first polymerization reactor and a second polymerization reactor that are connected with each other in sequence, wherein a first micro-interface generator is disposed outside the first polymerization reactor, and a second micro-interface generator is disposed inside the second polymerization reactor. A bottom of the second polymerization reactor is provided with a discharge port, and the discharge port is connected with a hydrogen halide removal tower. By disposing the first micro-interface generator in the first polymerization reactor while disposing the second micro-interface generator in the second polymerization reactor, on the one hand it increases the mass transfer area between the gas phase and the liquid phase material, improves reaction efficiency and reduces energy consumption, and on the other hand it results in a higher evenness of the poly-α-olefin and improved product quality.
