Films and rivulets are the two basic forms of dynamic liquid in a three-phase fixed bed (trickle bed), which determines the wetting efficiency of the catalyst. This paper is devoted to the conflicting wetting performance observed between non-porous glass beads and porous alumina pellets, and a parallel zone model is applied to resolve the complex liquid flow texture. This shows that in the case of glass beads, the wetting efficiencies of the catalyst along with the liquid flow rate in increasing and decreasing branches are different, especially when the gas flow rate is low. In comparison, there is almost no wetting difference for the alumina pellets with respect to liquid flow rate increasing or decreasing. The dynamic liquid is significantly more uniformly distributed over the cross-section in the Al2O3 bed than in the glass one.
