Abstracts
This study identified the loss of minimum fluidization velocity and pressure in accordance with the superficial velocity
of NiO/MoO3/MoS2, 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/MoO3/MoS2 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.
