The effect of fine adsorbent particles on gas - liquid mass transfer under distillation condition was studied in a bubble column

by using4A and 13X (in micron) as molecular sieve. It was found that the fine adsorbent particles cannot enhance gas - liquid mass transport unless adsorbents have strong adsorption on the less volatile components. The enhancement

however

has a limit up to a certain percentage of solids content

for example

about 10% in our experiment. Our experimental study confirms the predicted values from the model calculation.
