%X A measurement method of liquid circulation velocity and local gas holdup at high solid concentration in an airlift reactor simultaneously was developed,based on two probes of electrical conductivity tip and tracing method. Two residence time distribution (RTD) curves were obtained by measuring the concentration changes of tracer (saturated solution of KCl) injected into the riser by using two probes. The gas holdup was obtained by analyzing one RTD curve, with an average discrepancy within 5%. The liquid ci...
