Apparatus and process for alpha-olefin polymerization.

摘要

The fouling of the solid cocatalyst inlet nozzle in alpha-olefin Ziegler type polymerization in stirred liquid phase, mass reaction is reduced by positioning the inlet nozzle (30) below the liquid surface on substantially the same horizontal plane as the bottom impeller (20) and aligned with the impeller. The inlet nozzle extends from 30 to 80% of the distance between the wall (10) of the reactor and the tip (44) of the impeller. The ratio of the inlet velocity of the solid cocatalyst slurry to the reactor mass cross flow velocity is 2 - 3:1.
