Trickle bed reactors have been used in this study to examine flow regimes transition for evaluation and validation of computational fluid dynamics (CFD) and for developing the needed closures and interfacial forces models for water-air- solid system. The system of wet catalytic oxidation of phenol, present in refinery waste water, has been chosen as a model reaction to obtain the profiles. This work focuses on investigating the bubble dynamics (i.e. local gas holdup and bubble velocity) in trickle bed reactor. The oxidation reaction was examined in a 2 cm diameter and 80 cm length with a catalyst bed length of 32 cm. The residual phenol concentration and intermediate compound concentrations were used as a product model. Two advanced measurements were implemented in this work which were pressure transducer and fiber optical probe. The results of both techniques have been compared. The results show good overall agreement between the two methods and CFD simulation for the overall horizontal profile of both bubble size and gas holdup.
