The hydrodynamic of internal reactors with a riser diameter of 4cm and 5cm operating with air and
water system have been experimentally investigated for a range of superficial gas velocity. Here
we have used 2 internal loops with 4cm and 5cm internal diameter. For each velocity we have
measured the gas hold up. The gas phased sparged in to the column by means of 4 different
spargers with different number of holes in 1mm diameter. The results show that the gas distributer
plays an important role on the evolution of the bubble size distribution in gas-liquid reactor. So
one of the main subjects of the present work is to study the influence of sparger design.
