Some important characteristics of the bubbling regime, relevant to a cut of FCC catalyst with an average size of 110 mm were investigated at 100, 400 and 700 °C. This was achieved by imploying data of bed collapse tests as well as images of the bubble eruption at the free surface of the bed by varying fluidization velocities and bed aspect ratios. The results show that a smoother regime of fluidization is observed at superambient temperature.
