Process for introducing a solid catalyst into a gas-phase olefin polymerization reactor |
摘要 |
<p>The present invention relates to a process for introducing a solid catalyst into a gas-phase olefin polymerization reactor (10). It comprises in particular storing the catalyst in the form of a dry powder in a hopper (1), withdrawing from the hopper (1) a measured amount of the said catalyst, introducing the said amount of the catalyst and a liquid hydrocarbon into a mixing chamber (7), mixing the said catalyst with the said liquid hydrocarbon so as to form in the said chamber (7) a suspension of the entrained catalyst with the said liquid hydrocarbon, and introducing the said suspension into the said reactor (10). In a preferred form, the liquid hydrocarbon is continuously introduced into the chamber (7) and forms a continuous stream to which is added the measured amount of the catalyst and which flows into the reactor (10). <IMAGE></p> |
