A measuring approach of pressure oscillation has been developed and experiments are conducted in a 10 liter two-dimension air-lift loop reactor. The experimental results show that the local mass transfer parameters have close relationship with the operating conditions, the structure of ALR and the properties of the reaction systems. A series of measurements of pressure pulse indicate that a gas distribution zone exists near the gas sparger, and in this zone the responding signals of pressure pulse are different with the signals measured in other parts of the reactor.
