Abstract

Fremgangsmåte for oppstarting av en reaksjon for polymerisasjon av en olefin i gass- fasen utført ved bruk av en katalysator basert på kromoksyd i en reaktor med fluidisert sjikt gjennom hvilken det passerer en reaksjonsgassblanding inneholdende olefinen, og denne fremgangsmåten er kjennetegnet ved at det i oppstartingen av reaksjonen innføres olefin i reaktoren inntil den ønskede produksjon av polymer er nådd ved hjelp av en totrinnsprosess, idet innføringen av olefinen i løpet av det første trinnet i denne prosessen utføres slik at det opprettholdes et konstant partialtrykk for olefin i reaktoren og idet innføringen av olefin i løpet av det andre trinnet reguleres ved en konstant strømningshastighet.
