Abstract

After a kinetic study of catalytic oxidation of sulfur dioxide in aqueous slurry of fine particles of activated carbon, dp=20 μm, we used the same chemical reaction to study the performance of a three phase reactor formed by a jet venturi placed above a fixed-bed of crushed particles of activated carbon (dp=4.10^-3 m). Under variables operating conditions, some hydrodynamic characteristics are precised as well as the conductance of gas-liquid and liquid-solid mass transfer. Then, the sulfur dioxide oxidation is carried out in the verlifix reactor. The modelling of the reactor shows that the apparent reaction rate is strongly controlled by intraparticle diffusion.
