| Abstract: | :In this study, with the multicompartment rectangular air-lift loop reactor, gas velocity and liquid surface tension have been ecperimentally determined. The bubbles are divided into two categories, large bubbles and small bubbles. A drift flux model was adopted to describe the gas hold-up in the riser. Based on the principle of minimum energy dissipation an equation for the liquid circulation was derived. Meanwhile the gas hold-up (small bubbles and large bubbles), liquid circulation velocity and bubbles sizes, as wellas the relationships among them were studied. |

| Keywords: | Loop Gas hold-up Circulation Bubbles sizes. |
