摘要：
The effect of kinds of gas on gas holdup E(G) in bubble columns was studied. E(G) increased with increasing density of gas. This reason was explained as follows: Small bubbles easily generate in a heavy gas according to breakup of bubbles, because the dynamic pressure (rho (G)U(2)/2) in bubbles is large in heavy gas. Therefore, the quantity, or number of small bubbles for heavy gas becomes much larger than that for light gas and E(G) increases with increasing density of gas.
