Abstract

가압유동층 반응기에서 조업 중에 발생할 수 있는 가장 큰 문제는 agglomeration과 비산유출이다. 이런 현상은 정상조업 동안 보다는 시동 또는 정지시의 비정상상태에서 종종 발생한다. 유동층에서 가장 기본적이라고 할 수 있는 최소유동화속도와 종말속도의 이론적 고찰을 통해 가압유동층 반응기의 시동과 정지시 agglomeration과 비산유출을 방지할 수 있는 온도와 압력 조절범위의 적정궤적을 제안하였다.

Serious potential problems in pressurized fluidized bed reactors were agglomerations and entrainments, occurred often when the reactors were unsteady-states. Based on theoretical evaluations on minimum fluidization velocity and terminal velocity, optimum loci for the manipulation of temperature and pressure were proposed when the reactors were started-up and shut-down.
