摘要：
Ethylene is selectively oligomerized in a continuously stirred tank reactor (CSTR) that is preferably operated in an isothermal manner using a chromium catalyst. The undesired formation of by-product polyethylene is mitigated by contacting the ethylene with hydrogen prior to adding the ethylene to the reactor and feeding the ethylene and hydrogen via a common feed port.
