Fluidization Properties in Microscale Fluidized Beds
微小流化床流化特性分析

The fluidization characteristics of quartz sand and FCC catalyst particles in 6 microscale fluidized beds with inner diameters of 4.3,5.5,10.5,15.5,20.5 and 25.5 mm were investigated.The influences of bed diameter(Dt),static bed height(Hs),particles and gas properties on the pressure drop and minimum fluidization velocity(umf) were examined.The results show that the theoretical pressure drops of microscale fluidized beds deviated from the experimental values under different particles and gas properties.The ...
