⑷ Fluidized Bed
유체의 속도를 점점 증가시키면 압력 강하 및 각 입자에 대하여 항력이 증가하여 마침내 입자층이 올라가기 시작하며 유체층에 현탁된다. 이 때 현탁물의 거동이 밀도가 큰 유체와 같다. 유동층이 형성되면 윗면은 수평으로 유지되며, 큰 물체는 현탁액에 대한 상대적인 밀도에 따라서
of VOCs is 1.2 wt%
② Pseudo - Assumption
Rate determining step = Surface reaction
Almost catalyst reaction is determined by surface reaction
VOCs multi system = Toluene pure system
Average molecular weight = 90.5
Toluene’s molecular weight = 91.4
∴ Average molecular weight ≒ Toluene’s molecular weight
