Mass transfer in inverse fluidized beds

In this work, the coefficient of fluid-wall mass transfer in an inverse fluidized bed was determined using adsorption method. The experiments were carried out a column with diameter 45 mm spherical and non-spherical particles polypropylene polyethylene 3.3-4.9 density about 930 kg m-3. A diluted solution methylene blue used as fluidization medium, which adsorbed on part surface silica gel. obtained results showed that presence during does not contribute significantly to compared influence conventional beds. Therefore, pseudofluid concept introduced into analysis empirical correlation performed determine coefficient. literature correlations for
