The gas holdup is an important parameter in chemical and petroleum industries for coal gasification and catalytic synthesis of hydrocarbon. Experimental work was carried out to examine the effects of concentration of ionic (i.e., cationic and anionic) and non-ionic surface active agents on the gas holdup based on the particle size, slurry concentration, and superficial gas velocity. The change
in the volume fraction of gas was analyzed by the drift-flux model. An empirical correlation was developed. This correlation is suitable for predicting the gas holdup ranging from 2 to 22% within a wide range of slurry concentration.
