Abstract
U ovom diplomskom radu ispitan je utjecaj promjera radijalnog turbinskog miješala s četiri ravne lopatice (SBT miješalo) na proces sorpcije bakra na sintetskom zeolitu u kotlastom reaktoru, s i bez razbijala. Otopina bakra pripravljena otapanjem odgovarajuće mase Cu(NO 3 ) 2 u destiliranoj vodi. U eksperimentima je korišten sintetski zeolit NaX srednjeg promjera čestica 0,0765 mm. Ispitivanja su provedena pri stalnoj temperaturi (25 °C) suspenzije. Utjecaj promjera SBT miješala s četiri lopatice na kinetiku sorpcije ispitan je eksperimentima u kojima su korištena miješala različitih promjera (D/d T = 0,32; 0,46; 0,57; 0,68). Analiza dobivenih kinetičkih eksperimentalnih podataka primjenom Weber-Morrisovog i Blanchardovog modela pokazala je da difuzija ne utječe na ukupnu brzinu procesa, odnosno da ispitivana reakcija prati kinetiku drugoga reda u reaktoru s i bez razbijala virova. Rezultati ispitivanja pokazali su i da se povećanjem D/d T omjera i u reaktoru s i bez razbijala virova smanjuje utrošak snage miješanja.
Abstract (english)
In this diploma thesis, the influence of the diameter of the straight blade turbine (SBT impeller) with four blades on the copper sorption process of synthetic zeolite in a batch reactor with and without baffles was investigated. A copper solution was prepared by dissolving an appropriate amount of Cu(NO 3 ) 2 in distilled water. Synthetic zeolite NaX with an average particle diameter of 0.0765 mm was used in all experiments. The experiments were carried out at a constant temperature (25 °C) of the suspension. The influence of the diameter of SBT impeller with four blades on the kinetics of sorption was investigated by using impellers with different diameters (D/d T = 0.32; 0.46; 0.57; 0.68). The analysis of the obtained experimental kinetic data using the Weber-Morris and Blanchard models showed that diffusion does not affect the overall rate of the process, i.e. that the studied reaction in the reactor with and without baffles follows second order kinetics. The experiments results also showed that by increasing the D/d T ratio in both the reactor with and without baffles, the consumption of mixing power is reduced.
