NEW RESULTS OF MODELING OF REACTORS WITH PARTICLE ELECTRODES FOR THE ELECTROCHEMICAL WASTE TREATMENT

Following an estimation of the application of electrochemical methods for environmental protection, the central part of this work presents n ew results of mathematical modelling. Mathematical models for special flow regimes and bed geometries are described in relation to electroch emical fixed bed reactors, The model simulation was implemented with t he help of kinetic equations for copper deposition from sulutions cont aining sulphuric acid. Furthermore, the results of modelling, which ar e relevant to practise, are shown for the new VMPB-reactor, developed at the Technical University Kothen, e.g. the calculation of temperatur e- and concentration-time behaviour for electrochemical cells connecte d in seria and in parallel, or the time dependent behaviour of current density distribution across the particle bed, when the cell current i s held constant or variable with respect to time.
