Abstract�� The effects of superficial gas velocity and solid loading on gas holdup of the riser were investigated for the system of air-water-(K-resin) particles in multi-compartment airlift loop reactor,comprising a vertical column divided into four channels.The results showed that the gas holdup of one specified riser increased obviously with the increasing of the superficial gas velocity of the one specified channel and decreased slightly with that of other riser.The gas holdup of the riser decreased obviously with the increasing of the solid loading.Under the bubble flow regime,the model of the gas holdup of riser was established based on the drift-flux expression.The average relative error of gas holdup of the riser between calculated values and experimental values was 6.429%.
