Abstract

본 발명은 재순환 스트리임을 그것의 이슬점 이하로 냉각시키고 그 결과 생성된 두개-상을 가지는 스트리임을 반응기로 되돌아가게 하여 재순환 스트리임의 이슬점 이상의 바람직한 온도로 유동 베드를 유지시키도록 함으로써 발열 중합 반응을 이용한는 유동층 반응기에서 중합체 생성의 공시 수득량을 중가시키기 위한 공정에 관한 것이다.The present invention utilizes an exothermic polymerization reaction by cooling the recycle stream below its dew point and returning the resulting bi-phase stream to the reactor to maintain the fluidized bed at a desired temperature above the dew point of the recycle stream. It relates to a process for weighting the published yield of polymer production in a reactor.
