More Information
Summary: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. Léthylène est oligomérisé de manière sélective dans un réacteur à cuve à agitation continue (CSTR) qui fonctionne de préférence dune manière isotherme en utilisant un catalyseur de chrome. La formation non souhaitée dun sous-produit de polyéthylène est atténuée par la mise en contact de léthylène avec de lhydrogène avant lajout déthylène au réacteur et lintroduction déthylène et dhydrogène par un orifice dalimentation commun.
