In this work it is attempted to find a model describes potential,current, and concentration distributions in addition to hydrodynamicstudy along an electrochemical fluidized bed reactor. Electrochemicalfluidized bed reactor consists of a bed of particles which fluidizes andexpands by an upward moving electrolyte. An electrical potentialdifference is applied between the upper and lower parts of the bed which induces the electrochemical reaction to take place on thesurfaces of the particles.

By achieving simulation of hydrodynamics in a bubble column reactor,have taken an important step towards designing an efficient slurry reactor for large-scale conversion of synthesis gas to liquid hydrocarbons. The simulation allows determining gas holdup, a key variable affecting the reaction rate of gasto-liquid (GTL) conversion using Fischer-Tropsch (FT) chemistry.This information is important because there is the potential for the wide application of FT for conversion of refinery residues,an ever-increasing problem on a worldwide basis.
