METHOD FOR OLIGOMERISATION OF ETHYLENE AND REACTOR SYSTEM THEREFORE

摘要

THE PRESENT INVENTION RELATES TO A METHOD FOR THE OLIGOMERISATION OF ETHYLENE, COMPRISING THE STEPS OF: (I) OLIGOMERISING ETHYLENE IN A REACTOR IN THE PRESENCE OF A SOLVENT AND A CATALYST COMPOSITION; (II) DISCHARGING A CATALYST COMPOSITION CONTAINING OUTLET STREAM FROM THE REACTOR; (III) DEACTIVATING AND EXTRACTING THE CATALYST COMPOSITION WITH A POLAR PHASE, WHEREIN THE OUTLET STREAM AND THE POLAR PHASE ARE MIXED IN A DYNAMIC MIXING DEVICE HAVING ROTOR AND STATOR ELEMENTS COMPRISING CONCENTRIC TOOL RINGS AS WELL AS TO A REACTOR SYSTEM THEREFORE.
