초록

실험실 규모의 유동층 반응기(Length=0.25m, Diameter=0.05m)에서 고부가가치 물질인 희유금속 산화물 $NiO/MoO_3/MoS_2$의 공탑속도에 따른 최소유동화 속도 및 압력손실 경향을 확인하였다. 시료의 L/D 1, 2, 3 변화에 따른 Superficial gas velocity 0.07~0.45 m/s 범위에서 $NiO/MoO_3/MoS_2$의 L/D 1, 2, 3에서의 평균 압력손실은 Decreasing flux에서 290~1952 Pa, Increasing flux에서 253~1925 Pa로 나타났다. Wen이 제시한 이론값과 실험데이터를 비교해본 결과, 0.021~0.36배 차이나는 것을 확인하였다. 이번 결과를 통하여, 희유금속 산화물을 실제 현상에서 적용 가능한 운전조건을 결정할 수 있었다.

This study identified the loss of minimum fluidization velocity and pressure in accordance with the superficial velocity of $NiO/MoO_3/MoS_2$, a rare metallic oxide and high value-added material in the lab-scale fluidized bed reactor (L=0.25 m, D=0.05 m). The average pressure loss in L/D 1, 2, and 3 of $NiO/MoO_3/MoS_2$ within the scope of superficial gas velocity between 0.07 and 0.45 m/s based on the L/D 1, 2, and 3 of the specimen was shown to be 290~1952 Pa at decreasing flux and 253~1925 Pa at increasing flux. The comparison between the theoretical value proposed by Wen and the test data showed a difference between 0.021~0.36 magnification. Based on these results, this study was able to determine the operation conditions where rare metallic oxides could be applied in real phenomena.
