DEACTIVATION OF A PROCESS BY-PRODUCT

摘要

Processes of forming oligomers are described herein. The processes generally include contacting an olefin and a catalyst system to form an oligomerization product at oligomerization conditions, wherein a reaction system effluent includes components selected from the oligomerization product, a chromium containing compound and combinations thereof; and contacting the chromium containing compound with a beta-diketone at conditions capable of changing an oxidation state of chromium.
