MULTI REACTOR ETHYLENE OLIGOMERIZATION PROCESS WITH RECYCLE

摘要

A multi reactor system is used for the oligomerization of ethylene in the presence of a chromium/P-N-P catalyst system. The reactor system includes a mixed reactor and a tubular reactor. A portion of the reaction liquid is recycled back to the mixed reactor. The mixed reactor preferably contains a gas/liquid jet to facilitate the mixing of ethylene into the reaction liquid.
