Abstract
U ovom radu ispitan je utjecaj brzine miješanja na adsorpciju bakra na zeolitu NaX i utrošak snage miješanja. Otopina koja sadrži Cu 2+ ione pripravljena je otapanjem odgovarajuće mase Cu(NO 3 ) 2 ∙ 3H 2 O. Zeolit NaX samljeven je i prosijan na čestice veličine od 0,063 do 0,090 mm. Eksperiment se proveo u kotlastom reaktoru s razbijalima virova uz turbinsko miješalo s 4 lopatice pod kutom od 45° tzv. PBT. Kako bi se sagledao utjecaj brzine miješala na kinetiku adsorpcije, provedeni su eksperimenti pri četiri različite brzine vrtnje miješala uz stalnu temperaturu suspenzije. Kinetičkom analizom eksperimentalnih podataka Ritchievim i Weber-Morrisovim modelom uočeno je vrlo dobro slaganje dobivenih podataka s Ritchijevim modelom što ukazuje na to da reakcija prati kinetiku drugoga reda. Rezultati ispitivanja ukazali su i da se povećanjem brzine vrtnje PBT miješala povećava utrošak snage miješanja.
Abstract (english)
In this work, the influence of the mixing rate on the kinetics of copper adsorption on NaX zeolite and the mixing power consumption were investigated. A solution containing Cu 2+ ions with known initial concentration was prepared by dissolving the appropriate mass of Cu(NO 3 ) 2 ∙ 3H 2 O. The zeolite NaX was crushed and sieved to obtain particles of 0.063 to 0.090 mm. Mechanical mixing was performed with a turbine impeller with 4 blades at an angle of 45° so-called PBT in a batch reactor with baffles. To observe the influence of the impeller speed on the adsorption kinetics, experiments were performed at four different impeller speeds, while the suspension temperature was constant. The obtained experimental kinetics data were analyzed by Ritchie and Weber-Morris model. The kinetic analysis showed an agreement of the obtained data with the Ritchie model, which indicates that the reaction follows the second-order kinetics. The test results indicated that with the increasing speed of the PBT impeller, the power consumption increases.
