The emerging contaminants are commonly derived from municipal, agricultural, and industrial wastewater sources and pathways. These compounds are polar and poorly biodegradable. The dynamic removal of atenolol from aqueous solutions by activated carbon in fixed bed column systems was investigated. As far as we know, this is the first study reporting the decontamination by adsorption in fixed bed...

In this study, the homogeneity of the continuum model of a fixed bed reactor operated in steady state and unsteady state systems for lean CH4 oxidation is investigated. The steady-state fixed bed reactor system was operated under once-through direction, while the unsteady-state fixed bed reactor system was operated under flow reversal. The governing equations consisting of mass and energy balan...

This paper deals with geometric shape optimization of a parallelepiped shaped fixed-bed reactor single phase liquid flow where chemical reaction takes place. The packing is sort static mixer made up solid cylindrical obstacles uniformly distributed in the reactor. reactive described by means momentum and mass transport equations laminar regime. objective to determine that maximizes conversion r...

A lot of metallurgical processes take places in shaft furnaces, where reacting gas carrying powders flows up in packed bed of descending metallurgical materials. Gas + powder two phase flow in fixed packed bed has been investigated by author for many years 1 . At present author undertakes the investigations with moving bed. Physical model with glass bed and glass powders was constructed. The ex...

The Lattice Boltzmann Method (LBM) was used for simulation of a gas flow and conjugate heat transfer in fixed packed beds with solid particles inside. D2Q9 version of the Factorized Central Moment (FCMLBM) is used for a gas flow computation. Heating transfer in the bed is described by second distribution function set and multiple relaxation time lattice Boltzmann method (DDF MRT LBM) is used. N...
