چکیده

A four stage semi-pilot scale RFR reactor with ceramic disks as support for TiO2 modified 9 with silver particles was developed for the removal of organic pollutants. The design presented in 10 this article is an adaptation of the rotating biological reactors (RBR) and its coupling with the 11 modified catalyst provides additional advantages to designs where a catalyst in suspension is used. 12 The optimal parameter of rotation was 54 rpm and the submerged surface of the disks offer a total 13 contact area of 387 M2. The modified solid showed a decrease in the value of its bandgap compared 14 to commercial titanium. The system has a semi-automatic operation with a maximum reaction time 15 of 50 h. Photo-activity tests show high conversion rates at low concentrations. The results conform 16 to the Langmuir heterogeneous catalysis model. 17

Comparison of reverse flow and counter-current reactors in the case of selective catalytic reduction of NOx

The paper is focused on the comparison of the reverse flow reactor (RFR) and of the counter-current reactor (CCR) operation, focusing the attention on the interaction between transport phenomena and chemical reactions, as well as on the analysis of the dynamic behavior. A heterogeneous mathematical model was used in order to investigate the performance of both reactor configurations. The role o...

An experimental investigation and modelling of fluid flow in solar photocatalytic reactor for contaminated water treatment

Different types of solar photocatalytic reactors exists in the literature for water treatment, Thin-film fixed-bed reactor (TFFBR) is one of them which is used in this study because of its high surface area to volume ratio for water treatment. TFFBR is an inclined plate coated with P25 TiO2 DEGUSSA over which contaminated water flows during treatment. The TFFBR also contains a pump, by which th...
