Abstract
Sušenje u fluidiziranom sloju čest je proces za sušenje čestičnih materijala u kemijskoj i prehrambenoj industriji. U ovom radu istraživana je kinetika sušenja katalizatora u sušioniku sa fluidiziranim slojem. Mjerenja su provedena u laboratorijskom sušioniku pri različitim brzinama strujanja zraka, temperaturama ulaznog zraka, te različitim visinama sloja čvrstih čestica. Kao materijal za sušenje odabrane su čvrste sferične čestice tj. kuglice katalizatora zbog svog savršenog oblika. Kinetičke krivulje sušenja aproksimirane su odabranim matematičkim modelima, a njihovi su parametri dovedeni u vezu s uvjetima provedbe procesa. Rezultati su pokazali da temperatura i brzina strujanja zraka utječu na kinetiku sušenja, dok visina sloja čvrstih čestica nema značajan utjecaj na kinetiku sušenja. Veća brzina sušenja odgovara većim temperaturama i povoljnijim hidrodinamičkim uvjetima.
Abstract (english)
Fluidized bed drying is a common process for drying particulate material in chemical and food industry. In this work fluid bed drying kinetics of a catalyst has been investigated. Experiments were carried out in a laboratory fluid bed dryer at different drying air velocities, drying air temperatures and different catalyst bed heights. The examined material (catalyst) was selected for drying because of its particles spherical shape. Drying kinetic curves have been approximated with the chosen mathematical models and the resulting model parameters have been correlated with process conditions. Obtained results show that drying air temperature and drying air velocity influence the drying kinetics, while catalyst bed height doesn't show any significant influence on drying kinetics. Higher drying rates are obtained at higher temperatures and for adequate hydrodynamic conditions.
