 note = {The powders used in a fluidized bed have been classified into four groups by Geldart. The group C powder is adhesive, and it is difficult to establish good fluidization. The fluidization of the C powder has been recently studied as the fluidized beds are applied in various fields of industry.
In the present study, the fluidization quality of the C powder was investigated. The powders used in the experiments were alumina, aluminum hydrate and sodium carbonate, and the average diameter of them
was below 15 μm. It was found from the relationship between gas velocity and fluidization behavior that the fluidization quality of the C powder was strongly influenced by the bulk density of powder.
Low density powder tended to agglomerate, and high density powder tended to cause gas channeling. It is known that the maximum extent of the expansion of the emulsion phase increases with decreasing
particle diameter for the A powder. However, the expansion ratio decreased when the characteristic of the C powder was dominant. The boundary between the group C and A powders was estimated from the maximum point of the bed expansion.},
