Kinetics of phenol oxidation in a trickle bed reactor over active carbon catalyst
The wet air oxidation of phenol over a commercial active carbon catalyst was studied in a trickle bed reactor (TBR) in the temperature and oxygen partial pressure ranges of 120–160 ◦C and 0.1–0.2 MPa, respectively. The performance of the active carbon was compared in terms of phenol and COD destruction. The weight change of active carbon due to reaction was also measured. Finally, oxic phenol a...
متن کاملInfluence of Operational Parameters and Kinetic Modelling of Catalytic Wet Air Oxidation of Phenol by Al/Zr Pillared Clay Catalyst
Single and mixed oxide Al/Zr-pillared clay (Al/Zr-PILC) catalysts were synthesized and tested for catalytic wet air oxidation (CWAO) of aqueous phenol solution under milder conditions, in a semi-batch reactor. The catalysts were synthesized from natural bentonite clay using ultrasonic treatment during the aging and intercalation steps and were characterized <...
متن کاملStyrene Biofiltration in a Trickle-Bed Reactor
The biological treatment of styrene waste gas in a trickle–bed filter (TBF) was investigated. The bioreactor consisted of a two-part glass cylinder (ID 150 mm) filled with 25 mm polypropylene Pall rings serving as packing material. The bed height was 1m. Although the laboratory temperature was maintained at 22 °C, the water temperature in the trickle–bed filter was slightly lower (about 18 °C)....
متن کاملScale-up of strategies of a multi catalyst zone radio frequency heated micro trickle bed reactor
The scale up of an isothermal micro-trickle bed reactor operated under radio frequency (RF) heating has been performed. The effect of the reactor length, tube diameter and number of parallel tubes on the temperature non-uniformity parameter has been studied. The axial and radial temperature profiles were calculated using a 2D convection and conduction heat transfer problem with heat transfer pr...
متن کاملWater pollution abatement by catalytic wet air oxidation in a trickle bed reactor
Catalytic wet air oxidation of an aqueous phenol solution was carried out in a trickle bed reactor at mild conditions of temperature (120–160◦C) and oxygen partial pressure (0.6–1.2 MPa). Tests were performed at space times up to 1 h. A commercially available copper oxide supported over g-alumina was used as catalyst. The results show that the phenol conversion, the chemical oxygen demand (COD)...
