Abstract：Profiles of phase holdup in a f90 mm three-phase external loop airlift reactor using electrical resistance tomography and pressure transducers were investigated, water was used as the continuous and conductive phase, while polyurethane and air were non-conductive solid and gas phases, respectively. The results show that the gas holdup and solid holdup increases with the increase of superficial gas velocity, the solid holdup first increases with increasing superficial gas velocity and when ug=0.09 m/s, a constant value. For the fluidized system, the distribution of local solid and gas holdup shows a maximum at r/R=0~0.2, the radial gas and solid holdup increases with increase of gas velocity in the riser, while the radial gas and solid holdup is uniform in the downer. The feasibility of using the two techniques combined to measure the three-phase has been demonstrated.
