Abstract:
A solid shaped composite adsorbent for reducing deactivated catalyst residues and contaminants from a post polyolefin solution polymerization mixture is disclosed. The composite adsorbent comprises 70 - 90 wt% of an alumina component; 30 - 10 wt% of a clay component; and 0.5 - 3.5 wt% of at least one alkali metal component selected from the group consisting of elements in Group 1 A of the modern periodic table.
