Réacteurs à lit fixe catalytique à écoulement gaz-liquide

Abstract : The article deals with catalytic trickle bed reactor (CTBR) technology, which is widely used in the refinery and the petrochemical industries for hydro-treatments and partial oxidation reactions. A major difficulty in the reactor outlay is linked to the complexity of the gas-liquid flow (trickle) through the porous medium. Therefore, particular attention is given to the comprehension of the multiphase flow hydrodynamics. The phenomena observed at the scale of the catalytic particle, external and internal mass-transfer, are considered separately from the phenomena observed at the reactor scale, poor distribution of liquids, material and thermal axial and radial dispersion. The comprehension of these phenomena provides a reasoned approach to reactor modeling.
