A modified airlift reactor with an internal loop has been developed. The draught tube of the reactor is a net tube. The gas holdup and the volumetric gas-liquid mass transfer coefficient, kla, were investigated. Four net tubes with different mesh numbers were tested. The kla value of the proposed reactor with mesh sizes can double that of the airlift reactor at some high superficial gas velocities.
