The airlift loop reactor(ALR)with split draft tube iS a kind of multiphase reactor which has special gas-liquid flow pattern and mass transfer characteristics. For water-air system and sodium sulfite aqueous soultion(10%)-air system, the gas hold-up、oxygen consumption rate、specific gas-liquid interfacial area and volumetric mass transfer coefficient of ALR with split draft tube were measured at different superficial gas velocities, and were compared with those of ALR with single draft tube.At experimental superficial gas velocities (0~6cm/s),the parameters indicated above in-creased about 10%comparing with those of ALR with single draft tube. Since a special mem-brane gas distributor was used,great values of the parameters indicated above were obtained,and maximum values could be found at medium operating gas velocity (about 3 cm/s)
