Experiments were conducted to compare the two different type reactors-the one is an usual agitated batch reactor and the other a continuous flow reactor. The flow reactor used is named "Blast Tube Reactor" composed of one long pipe only. Into this pipe, liquid and high speed gas stream are introduced resulting highly atomized phase.
In such conditons, mass transfer and contact area between liquid and gas are surplizingly increased.
As the standard of comparison of reactor performances, mass-transfe rate of a definite material from one liquid phase to the other was measured.
In the 1st. report, using the apparatus of Fig. 1-1, phenol transfer rate from water phase to benzene was measured varying shapes, positions and r.p.m. of agitator under a definite ratio of liquid volume. (H₂O:C₆H₆=6:4)
Measured capacity coefficients are shown in Fig. 3-7.
In the 2nd. report, using the apparatus of Fig. 2-1, phenole or acetic-acid transfer rate from benzene phase to water was measured.
The flow-pattern of blast tube reactor are shown in Fig. 2-2.
Data obtained are summalized in Tab. 1. Fig. 2-5 is the reproduction of typical results obtained in the Ist. report and Fig. 2-4 is those of this report. Comparison of both figures shows that much improvement in capacity coefficients are obtained for the blast tube reactor.
