Dispersion and mass‐transfer characteristics and fluidization parameters influencing the performance of a small pilot‐plant immobilized enzyme reactor are evaluated. The suitability of a dispersed plug‐flow model to predict the conversions obtained in the enzymatic reaction (starch → glucose) catalyzed by amyloglucosidase immobilized to solid and porous carriers is assessed. The performance of a fluidized‐bed reactor is compared on the basis of a normalized residence time with that of a fixed bed and found to be superior.
